Creatine and Testosterone: Does Creatine Increase Testosterone?

The following blog post is for entertainment and informational purposes only. It is not intended to provide medical advice or diagnosis. Please consult your doctor before making any health-related decisions.

Creatine is one of the most studied supplements in sports nutrition, and it is also one of the most misunderstood when the conversation turns to hormones. A lot of gym chatter treats creatine like a mild steroid, and the question does creatine increase testosterone shows up constantly in forums, comment sections, and search results. The short answer, based on the available research, is no, not in any way that matters physiologically. This article looks at what creatine actually does, where the testosterone myth came from, and what actually supports healthy hormone levels over time.

What Creatine Actually Does in the Body

Creatine is not a hormone and it is not chemically related to testosterone or anabolic steroids. It is a naturally occurring compound made from amino acids, found in muscle tissue and in foods like red meat and fish, and it plays a role in the body's short-term energy system. Supplementing with creatine increases the amount of phosphocreatine stored in muscle, which helps regenerate ATP more quickly during brief, high-intensity effort like lifting or sprinting.

That mechanism explains why creatine can support strength, power output, and muscle recovery. It has nothing to do with how the testes or adrenal glands produce testosterone, which is why researchers have specifically tested whether creatine use has any measurable hormonal side effect, including on testosterone.

Does Creatine Increase Testosterone? What the Research Shows

According to a peer-reviewed review by the International Society of Sports Nutrition, which examined 13 separate studies on creatine and androgen levels, the current body of evidence does not indicate that creatine supplementation increases total testosterone, free testosterone, DHT, or causes hair loss. Two of the 13 studies reported small, short-term increases in total testosterone that the reviewers described as physiologically insignificant, while the remaining ten studies reported no measurable change at all.

That review is one of the more direct answers available to does creatine boost testosterone as a question, and it comes from a well-established sports nutrition research group rather than a single small study or a marketing claim. Based on that evidence, creatine testosterone research does not support the idea that supplementation raises hormone levels in any clinically meaningful way, in men or women.

The DHT Question: Where the Myth Started

Most of the creatine testosterone conversation actually traces back to a single 2009 study on college rugby players, not to testosterone itself. According to Cleveland Clinic, that study reported a 56 percent increase in dihydrotestosterone, or DHT, after seven days of creatine loading, and DHT is a hormone byproduct linked to hair thinning in people who are genetically predisposed to it. Total testosterone in that study did not change, only the DHT measurement did.

Cleveland Clinic also notes that no follow-up study has been able to recreate those results, and that twelve additional studies looking specifically at creatine and testosterone reported no significant hormonal increases. A 2025 randomized controlled trial published in the Journal of the International Society of Sports Nutrition tested this directly over 12 weeks in resistance-trained men, measuring total testosterone, free testosterone, and DHT alongside actual hair follicle health using trichogram and imaging tools. The trial found no meaningful differences between the creatine and placebo groups in DHT, DHT-to-testosterone ratio, or any hair growth measurement, which the authors describe as strong evidence against the idea that creatine affects hair or hormone levels. Between the 2021 review and this newer trial, the evidence available today answers does creatine increase testosterone about as clearly as a supplement question can be answered.

Why People Confuse Creatine's Performance Benefits With a Testosterone Boost

Part of the confusion comes from how creatine actually feels to use. Many people notice faster strength gains, better performance in the gym, and a fuller muscle appearance within the first couple of weeks, largely due to water retention inside muscle cells and improved training capacity. Those visible, felt changes get mentally linked to the kind of results people associate with higher testosterone, even though the underlying mechanism is completely different.

Creatine also gets lumped in with performance-enhancing substances in casual conversation because it is popular among strength athletes and bodybuilders, the same population that sometimes discusses anabolic steroids or unsupervised testosterone use. But creatine is not an anabolic steroid, does not suppress natural hormone production the way unsupervised steroid or testosterone use can, and does not require any cycling or provider oversight to use safely at typical doses. People weighing creatine against other approaches to muscle and strength goals, including questions about TRT dosage for bodybuilding, are often mixing two unrelated categories of supplement and therapy that work through entirely different biological pathways. Whether the underlying question is does creatine increase testosterone or does creatine boost testosterone enough to matter for training goals, the honest answer for both is that creatine's benefits come from the energy system, not the endocrine system.

What Actually Supports Healthy Testosterone Levels

Once the creatine testosterone question is settled, it helps to know what actually plays a measurable role. Sleep quality, body composition, and metabolic health are all connected to how the body regulates testosterone over time, which is also part of why testosterone and metabolism are closely linked in the research. Chronic sleep deprivation, excess body fat, and unmanaged metabolic conditions can all lower testosterone independent of any supplement routine.

The only way to know whether testosterone is actually low is through bloodwork interpreted by a licensed provider, not through how a supplement makes someone feel in the gym. Total and free testosterone, along with related markers, need lab context and a symptom history to mean anything clinically.

What Provider-Led Testosterone Evaluation Looks Like at Valhalla Vitality

Valhalla Vitality approaches testosterone concerns as a provider-led, AI-supported process built around lab data, not supplement trends or forum advice. A licensed provider reviews intake information and bloodwork before any testosterone therapy plan is proposed, and ongoing monitoring stays part of the process from there.

For people who have tried creatine or other supplements hoping to feel the effects of higher testosterone without actually raising it, a proper lab evaluation is the only way to find out what is really going on. Supplement history alone, including creatine testosterone speculation from a workout partner or a forum thread, is not a substitute for bloodwork. Options like testosterone replacement therapy are only appropriate when labs and symptoms support that path, and a provider is best positioned to make that call.

Frequently Asked Questions

Does creatine increase testosterone?

No. On the question of does creatine increase testosterone, a review of 13 studies by the International Society of Sports Nutrition found no evidence that creatine supplementation meaningfully increases total testosterone, free testosterone, or DHT.

Does creatine boost testosterone in any way for muscle growth?

Creatine supports muscle performance and recovery through its role in the body's energy system, not by changing testosterone levels. Strength and muscle gains from creatine happen independent of any hormonal effect.

Is the creatine and DHT connection real?

A single 2009 study reported a temporary DHT increase in rugby players, but no later study has reproduced that finding, including a 2025 randomized controlled trial that found no DHT or hair follicle differences after 12 weeks of use.

Can creatine cause hair loss because of testosterone or DHT changes?

Current research, including the 2025 trial that directly measured hair follicle health, does not support a link between creatine use and hair loss through DHT or testosterone pathways.

If creatine does not raise testosterone, how can I find out if my testosterone is actually low?

The only reliable way is bloodwork interpreted by a licensed provider alongside a review of symptoms and health history, not a supplement's effect on gym performance.

Is creatine safe to combine with testosterone replacement therapy?

Creatine is not a hormone and does not interact with testosterone therapy the way another hormone or steroid might, but anyone on TRT should mention all supplements to their provider so the full picture stays part of ongoing monitoring.

Talk to a Provider If You Are Concerned About Low Testosterone

Creatine remains a well-researched, generally safe supplement for strength and performance, but the research is clear on does creatine increase testosterone: it does not, and does creatine boost testosterone enough to notice does not hold up either. Anyone who suspects their testosterone is actually low deserves a real answer based on labs, not a supplement routine.

People who want to understand their own testosterone levels can start a provider-led evaluation with Valhalla Vitality and get answers grounded in bloodwork rather than gym-floor speculation.
