Does Creatine Raise Testosterone?

Creatine is best known for supporting strength, power and exercise performance. But because it can help you train harder and build lean muscle, it is sometimes described as a supplement that may increase testosterone.

So, does creatine actually raise testosterone?

Current evidence does not suggest that creatine works as a direct testosterone booster. It is not an anabolic steroid, testosterone replacement therapy or hormone treatment.

Instead, creatine primarily supports energy production during high-intensity exercise. This can improve training quality, strength and recovery, which may indirectly support some of the lifestyle and body-composition factors associated with healthy hormone levels.

There has also been interest in whether creatine affects dihydrotestosterone (DHT), another androgen hormone. However, the evidence remains limited and inconsistent.

In this guide, we look at what the research says about creatine and testosterone, how creatine supports muscle strength, its potential relationship with hormonal health, whether it is safe to take and what you can realistically expect from supplementation.

The Downsides of Low Testosterone Levels

Low testosterone can affect several areas of health, including sexual function, energy, mood, muscle and bone health.

In men, clinically low testosterone is commonly associated with reduced sex drive, fewer sexual thoughts, fewer morning erections, fatigue, depressed mood and reduced motivation. (1, 2)

However, these symptoms can also occur with stress, poor sleep, depression, medication side effects and chronic health conditions.

For this reason, low testosterone should generally be confirmed through blood testing and medical evaluation rather than assumed from symptoms alone.

Depending on the circumstances, this may include testing both total testosterone and free testosterone. (1, 2)

Muscle, Strength and Bone Health

Low testosterone can make it more difficult to maintain muscle mass, strength and physical performance.

Testosterone plays an important role in supporting lean body mass and normal red blood cell production. Low levels may therefore contribute to lower exercise tolerance and reduced physical performance. (1, 2)

Over time, clinically low testosterone can also contribute to lower bone mineral density, potentially increasing the risk of osteopenia, osteoporosis and fractures.

This becomes particularly relevant with age, when fall risk also increases. (1, 2, 3)

Sexual Health

Testosterone is closely connected to libido, so genuinely low levels may reduce sexual desire and contribute to fewer or weaker erections. (1, 4)

However, low testosterone does not explain every case of erectile dysfunction.

Erections also depend on blood flow, nerve function, cardiovascular health, diabetes status, stress and medication use.

Erectile dysfunction should therefore be evaluated by a healthcare professional rather than automatically attributed to testosterone levels. (1, 4)

Is Creatine Safe?

Creatine is generally considered safe for healthy adults when used appropriately.

Your body naturally produces creatine from amino acids, and smaller amounts are found in foods such as meat and fish. Supplementation simply provides a more concentrated amount than most people obtain through diet alone. (5, 6)

Some people may experience mild side effects, particularly when taking large doses or using a creatine loading phase.

Possible effects include temporary weight gain from increased water storage in muscle, bloating, nausea, stomach discomfort or diarrhea. (5, 7)

Digestive discomfort may be reduced by using smaller doses, taking creatine with food and staying adequately hydrated.

Creatine Supplementation for Muscle Strength

Creatine's performance benefits are not thought to come from increasing testosterone.

Instead, creatine helps support the regeneration of adenosine triphosphate, or ATP. ATP is a major source of usable energy within your cells, particularly during short bursts of intense activity.

When ATP loses a phosphate group, it becomes adenosine diphosphate. Phosphocreatine can donate a phosphate group to help regenerate ATP, making energy available again during demanding exercise. (5, 6)

This is one reason creatine can help improve performance during repeated high-intensity efforts such as resistance training or sprinting.

With more readily available energy, you may be able to perform additional repetitions, maintain power for longer or complete a higher-quality training session.

Over time, these small improvements in training quality can contribute to greater gains in strength and lean muscle when creatine is combined with an appropriate resistance-training program. (5, 6)

How Much Creatine Should You Take?

A common approach is to take around 3 to 5 grams of creatine monohydrate per day.

Another option is a loading phase, where a larger amount is taken for several days before transitioning to a smaller daily maintenance dose.

Loading can saturate muscle creatine stores more quickly, so some benefits may appear sooner. However, a loading phase is not required. (5, 6, 7)

A consistent daily dose can eventually achieve similar muscle creatine saturation while potentially reducing the likelihood of bloating or digestive discomfort associated with larger doses. (5, 6, 7)

So, Does Creatine Raise Testosterone?

Creatine does not appear to reliably increase testosterone in the way a hormone treatment or testosterone therapy would.

Its primary effects are related to cellular energy availability, exercise performance, strength and training capacity rather than directly stimulating testosterone production. (5, 6, 7)

That does not mean creatine is completely unrelated to hormonal health.

Any potential benefit is more likely to be indirect.

Creatine May Support Testosterone Indirectly Through Training

Resistance training is an important part of maintaining muscle, metabolic health and healthy body composition.

By helping improve performance during high-intensity exercise, creatine may make it easier to train consistently and maintain a higher-quality resistance-training program. (7, 11)

Better training can help preserve or increase lean muscle mass. Improvements in body composition and metabolic health may also support a healthier hormonal environment over time. (9, 12, 13)

Creatine may also help reduce fatigue during repeated high-intensity exercise and support some aspects of recovery, potentially making consistent training easier. (7, 11)

These benefits are more meaningful when combined with adequate sleep, a balanced diet, regular exercise and stress management.

However, this is very different from saying creatine directly boosts testosterone. Creatine is primarily a performance supplement, not a hormone treatment.

Does Creatine Increase DHT?

Dihydrotestosterone, or DHT, is another androgen hormone related to testosterone.

Interest in creatine and DHT largely stems from a small study of college-aged rugby players that reported changes in the DHT-to-testosterone ratio after creatine supplementation. (10)

However, this finding has not established that creatine consistently or clinically raises DHT across the wider population.

Reviews of the available research do not support treating creatine as a reliable DHT-boosting or testosterone-boosting supplement. More research is needed before stronger conclusions can be drawn. (7, 10)

Frequently Asked Questions

What Are the Negatives of Creatine?

The most common downsides are temporary water-weight gain and occasional digestive symptoms such as bloating, nausea or diarrhea, particularly with large doses or a loading phase. Creatine can also raise serum creatinine, which may affect interpretation of kidney blood tests without necessarily indicating kidney damage. (5, 7, 14)

What Happens After 1 Week of Creatine?

With a loading phase, muscle creatine stores rise faster, so water-weight gain, fuller-looking muscles and performance benefits may appear within the first week. A standard daily dose works more gradually but can reach similar saturation over time. (5, 6, 7)

Does Creatine Cause Weight Gain?

Yes. Early weight gain is usually caused by increased water storage inside muscle rather than body fat. Over time, creatine may also support greater lean mass gains when combined with resistance training. (5, 6, 7)

Is It Okay to Take Creatine When on Zepbound?

It may be appropriate for some people, but it is best discussed with the prescribing clinician. Zepbound can cause nausea, vomiting, diarrhea and dehydration, so creatine may be less appropriate during periods of poor fluid intake or significant gastrointestinal symptoms. (5, 15)

Does Creatine Increase LDL Cholesterol?

Creatine is not generally considered a supplement that raises LDL cholesterol, and LDL elevation is not commonly identified as an expected side effect. It should not, however, be used to treat high cholesterol or replace evidence-based cardiovascular care. (5, 6, 7)

Final Thoughts

Creatine is best understood as a performance supplement rather than a testosterone booster.

It supports energy production during high-intensity exercise, which can improve training quality, strength and lean muscle gains. These benefits may indirectly support some of the lifestyle and body-composition factors associated with healthy hormone levels. (5, 6, 7)

However, creatine does not appear to reliably raise testosterone directly, and it should not be considered an alternative to testosterone replacement therapy or medical treatment for clinically low testosterone.

If you are experiencing symptoms such as reduced libido, persistent fatigue or loss of muscle mass, the appropriate next step is medical testing rather than attempting to correct the problem with creatine alone.

For healthy adults interested in strength and exercise performance, creatine monohydrate remains one of the most extensively studied sports supplements available.
