Cordyceps for Energy, Stamina, Exercise Performance, Immune Health and Whole-Body Wellness
Cordyceps is one of nature's most extraordinary fungi.
For centuries, Cordyceps has been valued in traditional Asian wellness practices for vitality, stamina, resilience and restoration. Today, modern science is beginning to uncover why this unusual fungus attracted so much attention in the first place.
Human research has produced encouraging findings involving exercise capacity and measurable aspects of immune activity. Scientists are also investigating Cordyceps compounds for their relationships with cellular energy, metabolism, oxidative balance, inflammatory signaling, cognitive performance and healthy aging.
The story is still unfolding.
But Cordyceps is no longer interesting only because of tradition.
Controlled human studies have shown that particular Cordyceps preparations can create measurable changes in human physiology.
And that is where its modern story becomes especially fascinating.
What Is Cordyceps?
Cordyceps is not one single mushroom.
The name is commonly used for a group of related fungi famous for their extraordinary relationship with insects and other arthropods.
In nature, many Cordyceps-related fungi develop through an insect host before eventually producing a fruiting structure.
It is one of the stranger and more remarkable life cycles in the natural world.
Two names are especially important in wellness and research.
Ophiocordyceps sinensis
This is the organism historically known as Cordyceps sinensis. It grows naturally in high-altitude regions of the Tibetan Plateau and surrounding Himalayan areas and has a long history of traditional use.
Cordyceps militaris
This striking orange fungus can be cultivated much more readily and has become increasingly important in modern scientific research.
Although both are commonly discussed under the Cordyceps name, they are not identical.
Their chemical profiles can differ, which means the exact species and preparation used in research matter.
An Ancient Reputation for Vitality
Cordyceps has traditionally been associated with energy, stamina, recovery, respiratory wellness and vitality.
Traditional knowledge does not automatically establish a modern clinical benefit.
But it can point researchers toward interesting questions.
With Cordyceps, one of those questions became especially compelling:
Could its centuries-old reputation for vitality have a measurable biological foundation?
Researchers began investigating exercise capacity, oxygen utilization, cellular energy and fatigue.
Some human studies produced encouraging answers.
Cordyceps and Exercise Capacity
One particularly interesting human trial involved healthy adults between 50 and 75 years old.
Participants received either a cultured Cordyceps preparation known as Cs-4 or placebo three times daily for 12 weeks.
The Cordyceps group received 333 milligrams three times daily, for a total of 999 milligrams per day.
After 12 weeks, researchers measured a:
10.5% increase in metabolic threshold
and an
8.5% increase in ventilatory threshold.
Comparable significant changes were not observed in the placebo group.
These measurements deserve some explanation because they tell us considerably more than the numbers alone.
What Is Metabolic Threshold?
As exercise becomes more intense, the muscles eventually reach a point where lactate begins accumulating more rapidly.
The metabolic threshold helps describe where that transition occurs.
A higher threshold means a person can exercise at a greater intensity before reaching that point.
In the Cordyceps study, metabolic threshold increased by 10.5% after 12 weeks.
That is an encouraging human finding related to exercise capacity and stamina.
What Is Ventilatory Threshold?
As exercise intensity increases, breathing eventually begins increasing disproportionately to the workload.
That transition is called the ventilatory threshold.
It is another useful measurement of aerobic exercise capacity.
The Cordyceps group experienced an 8.5% increase in this measurement.
VO₂ max did not significantly change.
That actually teaches us something useful.
Exercise performance is not represented by one number.
Cordyceps affected particular exercise thresholds in this study even though maximal oxygen capacity remained unchanged.
Cordyceps and Stamina
These findings become particularly interesting when considered alongside Cordyceps' long traditional association with stamina and vitality.
Human research has investigated outcomes involving:
Exercise capacity
Metabolic threshold
Ventilatory threshold
Oxygen utilization
Time to exhaustion
Aerobic performance
Recovery
Results have varied among studies and populations.
Highly trained athletes, for example, have not consistently experienced the same improvements seen in some other populations.
Training level may be important.
A highly conditioned athlete has already developed substantial adaptations in cardiovascular function, muscular efficiency and oxygen utilization.
Age, training status, Cordyceps preparation, amount and duration of supplementation may all influence the response.
Researchers are still learning which people and which preparations may benefit most.
Cordyceps and Cellular Energy
To understand why scientists became interested in Cordyceps and energy, it helps to understand ATP.
ATP stands for adenosine triphosphate.
It is one of the body's fundamental energy molecules.
Muscles require ATP to contract.
Nerve cells require energy to communicate.
The heart needs a continuous energy supply to beat.
Virtually every living cell depends upon energy to perform its work.
Cordyceps contains nucleosides and other compounds that have led researchers to investigate its relationship with energy metabolism and physical performance.
The idea is not that Cordyceps simply supplies the body with a burst of energy.
The more interesting scientific question is whether compounds within Cordyceps interact with the biological systems involved in producing, regulating and using cellular energy.
Cordycepin
One of the most fascinating compounds associated with Cordyceps militaris is cordycepin.
Its scientific name is 3'-deoxyadenosine.
Cordycepin resembles adenosine, a naturally occurring molecule involved in numerous biological processes.
That structural similarity allows researchers to investigate how cordycepin interacts with cellular pathways.
Areas being studied include:
Cellular signaling
Energy metabolism
Immune responses
Inflammatory pathways
Oxidative balance
Cellular growth and behavior
Cordycepin is one reason Cordyceps militaris has become such an important species in modern Cordyceps research.
Cordyceps and Immune Health
Human immune research provides another particularly interesting part of the Cordyceps story.
In a randomized controlled study involving 79 healthy men, 39 participants received 1.5 grams per day of an ethanol-treated Cordyceps militaris preparation while 40 received placebo for four weeks.
Researchers measured several aspects of cell-mediated immunity.
Compared with placebo, the Cordyceps group experienced significantly greater increases in several measurements, including:
Natural killer cell activity
Lymphocyte proliferation
Interleukin-2
Interferon-gamma
These findings are especially interesting because researchers measured biological changes in immune activity rather than relying solely on how participants said they felt.
What Are Natural Killer Cells?
Natural killer cells, usually shortened to NK cells, are part of the body's innate immune system.
Innate immunity is one of the body's rapid-response defense systems.
NK cells help recognize and respond to certain infected or abnormal cells.
Scientists can measure their activity.
The finding that Cordyceps militaris influenced NK-cell activity in a controlled human study provides an important bridge between experimental Cordyceps research and actual human biology.
What Are Lymphocytes?
Lymphocytes are white blood cells that play central roles in immunity.
Different types of lymphocytes perform different jobs, including recognizing threats, coordinating immune responses, producing antibodies and creating immune memory.
The Cordyceps study found increased lymphocyte proliferation.
That means researchers observed measurable changes in the activity of these important immune cells.
What Are IL-2 and Interferon-Gamma?
Interleukin-2, commonly called IL-2, is a signaling molecule involved in communication and activity among immune cells.
Interferon-gamma, or IFN-gamma, is another immune signaling molecule involved in coordinating cellular immune responses.
The fact that these measurements changed alongside NK-cell activity and lymphocyte proliferation gives researchers several different pieces of evidence suggesting that this particular C. militaris preparation influenced cell-mediated immune activity.
Another Human Immune Study
The immune story does not rest on one trial alone.
A later randomized controlled clinical trial investigated a fermented Cordyceps militaris beverage in healthy men and women.
Researchers again observed changes involving natural killer cell activity.
In men, NK-cell activity increased after four weeks compared with baseline. In women, NK-cell activity was significantly greater than placebo after eight weeks.
The study also monitored blood and metabolic safety measurements.
This provides another layer of human evidence suggesting that particular Cordyceps militaris preparations can interact with measurable aspects of immune function.
Immune Support Is About Balance
The immune system is far more sophisticated than an accelerator pedal.
Healthy immunity requires coordination.
The body must recognize potential threats.
It must activate an appropriate response.
And it must know when to regulate that response.
A useful scientific concept here is immunomodulation.
Immunomodulation means influencing or regulating immune activity.
Cordyceps is interesting because researchers are finding interactions with several different components of immune signaling rather than one simple "on" switch.
Cordyceps Polysaccharides
Cordyceps contains large carbohydrate molecules called polysaccharides.
These are among the fungal compounds being investigated for biological activity.
Researchers are exploring Cordyceps polysaccharides in connection with:
Immune signaling
Antioxidant defenses
Glucose metabolism
Lipid metabolism
Inflammatory balance
Gut microorganisms
Different Cordyceps species and cultivation methods can produce different polysaccharides.
That is another reason the word "Cordyceps" on a supplement label does not tell the whole story.
Beta-Glucans
Some fungal polysaccharides belong to a family called beta-glucans.
Beta-glucans occur naturally in fungal cell walls and have attracted considerable attention for their interactions with immune biology.
Some mushroom supplements provide measured beta-glucan content.
That can offer useful information about the fungal material in a product.
A label advertising only "total polysaccharides" provides less specific information because polysaccharides can also originate from grain or other ingredients used during cultivation.
Cordyceps and Cognitive Performance
A fascinating new direction appeared in human Cordyceps research in 2026.
In a randomized, double-blind, placebo-controlled crossover trial, 12 recreationally active young men received either 1 gram of standardized Cordyceps militaris extract or placebo before a maximal cycling test.
Participants had faster post-exercise reaction times in the Cordyceps condition than in the placebo condition.
Researchers measured reaction time using a Stroop task, a test involving attention and response speed.
Accuracy remained extremely high in both conditions.
The study also found that resting oxygen uptake was higher after Cordyceps, while peak exercise oxygen uptake was not significantly different.
Because the trial included only 12 young men, this is an early human finding rather than evidence of a broad cognitive benefit.
But it opens an intriguing new research question:
Could Cordyceps influence particular aspects of cognitive performance surrounding physical exertion?
That question now deserves further study.
Cordyceps and Oxygen Use
Cordyceps is sometimes described as helping the body "use oxygen better."
There is scientific interest behind that idea, but human physiology is more complicated than the phrase suggests.
Scientists measure several aspects of oxygen utilization during exercise.
One is VO₂, which refers to the amount of oxygen the body uses.
VO₂ max represents the maximum amount of oxygen a person can use during intense exercise.
But VO₂ max is only one measurement.
Researchers also examine metabolic threshold, ventilatory threshold and other physiological responses.
This helps explain how a Cordyceps study can find encouraging changes in exercise-related measurements even when VO₂ max itself does not change.
Cordyceps and Exercise Recovery
Scientists are also looking beyond what happens during exercise.
Physical activity temporarily changes:
Muscle metabolism
Oxidative balance
Inflammatory signaling
Energy demands
Cellular stress
Researchers are investigating whether Cordyceps compounds influence the body's response during recovery.
This remains an emerging area, but it fits naturally with the broader research into stamina, energy metabolism and physical resilience.
Cordyceps and Fatigue
Traditional Cordyceps use has long included fatigue and vitality.
Modern researchers are investigating possible explanations involving energy metabolism, oxidative balance and physical performance.
Fatigue itself is complex.
Sleep, nutrition, physical conditioning, stress, hormones, illness and many other factors influence how energetic someone feels.
Cordyceps therefore makes the most sense as something being investigated for physiological energy and stamina rather than as a universal answer to tiredness.
Cordyceps and Antioxidant Defenses
Normal cellular metabolism continuously produces reactive molecules.
The body maintains sophisticated antioxidant systems to help keep these molecules balanced.
When that balance becomes disrupted, scientists call it oxidative stress.
Cordyceps compounds have demonstrated antioxidant-related activity in experimental research.
Scientists are investigating whether these interactions contribute to some of the relationships observed with metabolism, exercise and cellular resilience.
Cordyceps and Inflammatory Balance
Inflammation is part of normal human biology.
The body's inflammatory response helps coordinate healing and defense.
The goal is not to eliminate inflammation.
The goal is appropriate regulation.
Cordycepin and Cordyceps polysaccharides have demonstrated interesting interactions with inflammatory signaling pathways in experimental research.
This remains an active area of scientific exploration.
Cordyceps and Metabolic Wellness
Researchers are also studying Cordyceps compounds in relation to metabolism.
Areas of interest include:
Glucose regulation
Insulin signaling
Lipid metabolism
Mitochondrial activity
Cellular energy pathways
Oxidative balance
The mitochondria are structures inside cells that help convert nutrients into usable cellular energy.
Because Cordyceps has such a longstanding association with vitality, its possible interactions with energy metabolism are particularly intriguing.
Much of this metabolic research remains experimental, but it may eventually help scientists understand the broader biological story.
Cordyceps and Healthy Aging
Cordyceps has also become popular in the world of healthy-aging wellness.
The connection makes sense from a research perspective.
Scientists studying aging are deeply interested in:
Cellular energy
Mitochondrial function
Immune regulation
Oxidative balance
Metabolic health
Physical capacity
Cordyceps research intersects with several of these areas.
That does not mean Cordyceps has been shown to extend human lifespan.
Its more meaningful connection with healthy aging lies in research surrounding biological systems that help people remain energetic, active and resilient as they grow older.
The encouraging exercise-threshold findings in adults ages 50–75 make that question particularly interesting.
Cordyceps and Kidney Research
Cordyceps preparations have also been studied in people with kidney conditions, particularly in Asian clinical research.
Some studies have reported favorable changes in kidney-related measurements when particular Cordyceps preparations were used alongside conventional treatment.
Study quality has varied, and stronger clinical trials are still needed.
This research nevertheless demonstrates how far scientific interest in Cordyceps extends beyond energy and exercise.
Cordyceps and Cardiovascular Wellness
Experimental research has examined Cordyceps compounds in relation to:
Circulatory biology
Lipid metabolism
Oxidative balance
Platelet activity
Cellular signaling
Heart metabolism
Human evidence in this area is less developed than the exercise and immune research.
For now, cardiovascular wellness is best understood as an area researchers are exploring.
Cordyceps and Sexual Vitality
Cordyceps also has a long traditional association with sexual vitality and reproductive wellness.
Modern researchers have investigated reproductive and hormonal pathways, particularly in experimental models.
Human evidence remains limited.
This makes sexual vitality an interesting part of the traditional Cordyceps story and another area where modern research is still developing.
Wild Cordyceps
Wild Ophiocordyceps sinensis has an extraordinary natural history.
It develops in high-altitude environments through a relationship with caterpillar larvae living beneath the soil.
Eventually, the fungus produces a slender fruiting structure above ground.
For generations, this unusual combination of fungus and insect became highly valued.
As demand increased, wild Cordyceps became extraordinarily expensive.
Heavy harvesting and environmental pressures have also increased interest in sustainable cultivation.
Cultivated Cordyceps
Cultivation has transformed the modern Cordyceps world.
Instead of depending entirely on scarce wild material, producers can grow particular Cordyceps species under controlled conditions.
Cultivation offers potential advantages involving:
Sustainability
Species identification
Controlled growing conditions
Consistency
Contaminant testing
Availability
Research standardization
Cultivated Cordyceps is not "fake Cordyceps."
It is fungal material grown under controlled conditions rather than harvested from the wild.
Cordyceps Militaris
Cordyceps militaris has become especially important because it can be cultivated and naturally produces cordycepin.
Its vivid orange fruiting bodies are dramatically different from the slender wild O. sinensis people may have seen in photographs.
Some of the most interesting modern human immune research involves C. militaris.
That makes the exact species worth looking for on a supplement label.
What Is Cs-4?
Another name that appears in Cordyceps research is Cs-4.
Cs-4 is a cultured Cordyceps preparation associated with Ophiocordyceps sinensis.
It has been used in human clinical research, including the 12-week exercise study in adults ages 50–75.
That study used 333 milligrams three times daily, totaling 999 milligrams per day.
This illustrates why Cordyceps research must be read carefully.
A study involving Cs-4 is not necessarily studying the same material as a study involving a Cordyceps militaris extract.
Both belong to the larger Cordyceps story.
But they are not identical preparations.
Fruiting Body and Mycelium
The fruiting body is the reproductive structure produced by a fungus.
Mycelium is the network of fine fungal threads from which the fungus grows.
Cordyceps supplements may contain:
Fruiting-body material
Mycelium
Cultured fungal preparations
Extracts
Their chemical compositions can differ.
Marketing sometimes turns this into a simple argument that fruiting bodies are always good and mycelium is always inferior.
The research story is more complicated.
Some human Cordyceps research has been conducted using cultured fungal or mycelial preparations.
The more useful questions are:
What species is being used?
What preparation is included?
How was it grown?
How was it extracted?
What compounds are present?
Has the finished product been tested?
Mycelium Grown on Grain
Some fungal supplements are produced by growing mycelium on rice, oats or another grain.
The finished material may therefore contain fungal mycelium along with remnants of the growing substrate.
That does not automatically make a product poor quality.
But consumers deserve transparency.
A thoughtful label should make it reasonably clear what is actually inside the bottle.
Extract Ratios
Cordyceps extracts sometimes carry numbers such as:
8:1
or
10:1
These ratios generally describe the amount of starting material used relative to the resulting extract.
A higher ratio does not automatically mean a better supplement.
An extract ratio cannot tell us everything about:
Species identity
Cordycepin
Beta-glucans
Purity
Contaminants
Bioavailability
Finished-product quality
Numbers can look impressive on a bottle.
Testing tells us considerably more.
Cordycepin Content
Some Cordyceps militaris products disclose their measured cordycepin content.
That can be useful because cordycepin concentrations can vary according to fungal strain, cultivation, harvesting and processing.
Science has not established one ideal cordycepin concentration for general wellness.
More is not automatically better.
The important point is that modern testing allows consumers and researchers to understand the composition of Cordyceps products more precisely than ever before.
Beta-Glucan Content
Measured beta-glucan content can also provide useful information about fungal material.
It should not be treated as the only marker of quality.
Cordyceps contains numerous compounds that may contribute to its biological activity.
A thoughtful product evaluation considers the whole picture rather than chasing one impressive number.
How Much Cordyceps Has Been Studied?
There is no universal evidence-based Cordyceps dose because different human studies have used different preparations.
For example:
999 milligrams per day of Cs-4 was used for 12 weeks in the exercise study involving adults ages 50–75.
1.5 grams per day of an ethanol-treated C. militaris preparation was used for four weeks in the 79-person immune study.
1 gram of standardized C. militaris extract was used as a single dose in the 2026 exercise and reaction-time study.
Those amounts cannot automatically be treated as equivalent because the preparations themselves were different.
This is why the product and preparation matter as much as the number of milligrams.
How Long Has Cordyceps Been Studied?
Human studies have examined very different timelines.
Some investigate a single dose.
Others have studied regular supplementation for:
Four weeks
Eight weeks
Twelve weeks
This suggests Cordyceps should not necessarily be thought of as something that must create an immediate sensation.
Some of the most interesting human findings appeared after regular supplementation.
When Do People Take Cordyceps?
Cordyceps is commonly taken:
In the morning
Earlier in the day
Before physical activity
With breakfast or another meal
There is no universally established time everyone needs to take it.
The particular product and individual response matter more than the clock.
Does Cordyceps Contain Caffeine?
Cordyceps itself is not naturally caffeinated.
This is one reason people interested in energy and stamina sometimes find it appealing.
Cordyceps is also frequently included in mushroom coffees, energy drinks and pre-workout products.
Those products may contain caffeine from coffee, tea or other ingredients.
The complete ingredient list tells the real story.
Is Cordyceps a Stimulant?
Cordyceps is not a conventional stimulant like caffeine.
Its relationship with energy is more interesting than simple stimulation.
Researchers are investigating exercise physiology, cellular metabolism, oxygen utilization and physical capacity.
That makes the Cordyceps energy story fundamentally different from simply drinking another cup of coffee.
What Does Cordyceps Feel Like?
There is no universal Cordyceps sensation.
Some people describe greater energy or stamina.
Others may notice very little subjectively.
Human research reminds us that a biological effect does not necessarily have to produce a dramatic feeling.
Changes in exercise thresholds or immune-cell activity, for example, are measured rather than necessarily felt as an immediate burst of energy.
Cordyceps Safety
Cordyceps preparations used in human studies have generally been well tolerated during the periods studied.
In the 79-person immune trial, researchers reported no statistically significant adverse reaction.
In the 2026 crossover trial of standardized C. militaris, all 12 participants completed both conditions without adverse events.
Reported side effects associated with Cordyceps are generally mild and may include digestive discomfort in some people.
Larger and longer human studies will continue expanding what we know about long-term use.
Cordyceps and Medications
Because Cordyceps contains biologically active compounds, interactions are possible.
Particular attention may be appropriate for people using:
Blood-sugar-lowering medication
Anticoagulant medication
Antiplatelet medication
Medications that substantially alter immune function
This is not unique to Cordyceps.
Whenever a natural substance meaningfully interacts with human biology, it can potentially interact with medications affecting some of the same systems.
Pregnancy and Breastfeeding
Human Cordyceps research during pregnancy and breastfeeding remains limited.
We therefore do not have the same evidence base for these stages of life that we have for healthy nonpregnant adults.
Choosing a Cordyceps Supplement
Cordyceps is a wonderful example of why supplement quality matters.
Look beyond the artwork and promises on the front of the bottle.
Useful information includes:
Exact Cordyceps species
Fruiting body, mycelium or cultured preparation
Extract information
Amount per serving
Beta-glucan testing when available
Cordycepin testing when relevant
Independent testing
Transparent ingredient labeling
Quality testing may also examine:
Heavy metals
Microbial contamination
Pesticides
Identity
Purity
A label saying only Cordyceps leaves many questions unanswered.
A transparent manufacturer should be able to tell consumers considerably more.
Wild Does Not Automatically Mean Better
The word wild has a powerful appeal.
But wild Cordyceps is not automatically superior.
Wild material can vary according to geography, environment and harvesting conditions.
Cultivation can provide greater consistency while reducing pressure on wild populations.
A carefully cultivated, identified and tested Cordyceps militaris product can therefore make excellent sense.
Nature gives us the organism.
Thoughtful cultivation allows us to work with it responsibly.
What Human Research Has Already Shown
Cordyceps research is still growing, but several human findings deserve recognition.
Improved metabolic threshold
A 12-week Cs-4 trial reported a 10.5% increase in adults ages 50–75.
Improved ventilatory threshold
The same trial reported an 8.5% increase.
Influenced natural killer cell activity
Controlled human studies involving Cordyceps militaris have measured changes in NK-cell activity.
Increased lymphocyte proliferation
This was demonstrated in a randomized study involving healthy men.
Influenced immune signaling molecules
Human research has measured changes involving IL-2 and interferon-gamma.
Was associated with faster reaction time in a small human trial
A 2026 randomized crossover study found faster post-exercise reaction times in the Cordyceps militaris condition than in the placebo condition.
These findings do not mean every Cordyceps product will produce every effect in every person.
They tell us something more useful:
Particular Cordyceps preparations have demonstrated measurable biological activity in controlled human research.
And that gives scientists strong reasons to keep asking questions.
Where Cordyceps Research Is Going Next
Some areas of Cordyceps research are further along than others.
Human research gives us encouraging information involving exercise physiology and immune activity.
Researchers are continuing to explore:
Exercise recovery
Metabolism
Mitochondrial function
Cognitive performance
Inflammatory signaling
Antioxidant defenses
Cardiovascular biology
Healthy aging
Kidney health
Gut microbiome interactions
Some of tomorrow's most interesting Cordyceps discoveries may come from questions researchers are only beginning to ask today.
An Extraordinary Fungus With an Extraordinary Story
Cordyceps does not need exaggerated promises to be remarkable.
Its real story is better.
A fungus with one of nature's strangest life cycles became valued by humans centuries ago.
Traditional practitioners associated it with vitality and resilience long before anyone could measure metabolic thresholds, identify natural killer cells or isolate cordycepin.
Modern science arrived later with microscopes, exercise laboratories, immune assays and molecular analysis.
And gradually, pieces of that ancient reputation began appearing in measurable human biology.
Not every traditional use has been confirmed.
Not every modern hypothesis will ultimately be supported.
That is how discovery works.
But Cordyceps has already crossed an important threshold.
It is no longer simply an ancient story.
It is a living field of human research.
Bringing It All Together
Cordyceps sits beautifully at the meeting point between traditional wisdom and modern science.
Controlled human research has produced encouraging findings involving exercise thresholds, physical capacity and measurable aspects of immune activity.
Emerging human research is beginning to investigate cognitive performance and other areas.
Laboratory research is opening still more doors involving metabolism, cellular energy, oxidative balance and healthy aging.
There is much left to learn.
But what we already know gives us plenty to appreciate.
Cordyceps contains a complex collection of natural compounds.
Its different species and preparations are not identical.
Its effects may vary according to age, fitness level, formulation, amount and duration.
And its biology continues to surprise researchers.
Perhaps that is the most beautiful part of the Cordyceps story.
Something does not have to be completely understood to be worthy of exploration.
Sometimes nature gives us the first clue.
Tradition preserves the question.
And science slowly begins revealing the answer.
