What Creatine Does to DHT (And Why It’s One of the Most Under-Discussed Effects of the Supplement)

Quick Review: Creatine Monohydrate and DHT

Creatine monohydrate is the most well-studied supplement in sports science and one of the few in my protocol I’d call universally worth it. The DHT effect — which came from one widely-cited study and has been mostly misunderstood ever since — is real but modest, and the framing around it has caused more unwarranted fear than warranted concern. For most men, this is a non-issue. For men with significant genetic predisposition to androgenetic alopecia, it’s worth knowing about but not worth losing sleep over.

• Best for: Almost everyone. Strength, body composition, cognitive function, creatine deficiency correction. The DHT effect is a side note, not the main story.
• Dosage I use with clients: 3–5g daily, no loading phase needed. Creatine monohydrate, not fancy forms. Take it with food, timing doesn’t matter much.
• Cycling protocol: No cycling needed. Creatine is not suppressive and doesn’t require breaks. Indefinite daily use is fine.
• Would I recommend it: Yes, without qualification for most men. The hair loss concern should be understood and contextualized, not used as a reason to avoid one of the most effective supplements available.

The creatine-DHT story started with a single study — a reasonably well-designed trial on college rugby players that showed creatine supplementation raised DHT and the DHT-to-T ratio over three weeks. That study got picked up by fitness media, the DHT-hair loss connection was invoked, and a significant number of men started avoiding one of the most effective supplements available because of a mechanism they’d half-understood from a summary of a single paper.

Let me explain what actually happened in that study, why DHT raising is mostly not the concern people think it is, and when it actually is worth paying attention to.

The Mechanism — What Creatine Does to 5-Alpha-Reductase

The finding was specific: creatine supplementation increased (5-alpha-reductase, or 5-AR, the enzyme responsible for converting testosterone into the more potent androgen DHT) 5-alpha-reductase activity — particularly Type 1, which is present throughout the body — resulting in higher DHT and a higher DHT-to-T ratio. Total testosterone didn’t change meaningfully in most creatine studies. This is a key distinction that gets lost in most coverage: creatine doesn’t raise testosterone. It appears to shift how efficiently the body converts testosterone to DHT.

Why would creatine do this? The honest answer is we don’t know for certain. Creatine’s primary mechanism is ATP regeneration — it increases phosphocreatine stores in muscle, allowing faster ATP recycling during high-intensity effort. How this connects to 5-AR activity is not fully established. The leading hypothesis is that creatine’s effects on cellular energy status may indirectly influence steroidogenic enzyme activity, but this hasn’t been proven mechanistically in humans.

What we do know from the pattern across multiple studies: creatine monohydrate consistently improves strength, body composition, power output, and in several trials, cognitive function. The DHT finding has been replicated in some subsequent work but not others. The magnitude of the DHT increase in the original study was roughly 56% above baseline — which sounds large but must be contextualized against what that means in absolute terms for men whose DHT is already in the reference range.

The Hair Loss Question — Honest Answer

(Androgenetic alopecia, or male pattern baldness, is driven by DHT binding to androgen receptors in genetically sensitive scalp follicles, causing them to miniaturize over time) Androgenetic alopecia is DHT-dependent. Men with scalp follicles that express high androgen receptor density are more sensitive to DHT at the scalp level. Finasteride and dutasteride work for hair loss specifically because they block 5-alpha-reductase and reduce DHT — and they work, which confirms that DHT is causal.

Does creatine accelerate hair loss? For men without genetic predisposition to male pattern baldness, the answer is almost certainly no — they don’t have the follicular androgen receptor density that would respond to marginal DHT increases. For men with significant genetic predisposition who were already losing hair, creatine may marginally accelerate something that was going to happen anyway. The word “marginally” is doing real work in that sentence. We’re talking about a modest increase in DHT from a supplement, not pharmaceutical-level 5-AR upregulation.

This is the conversation I had with Greg Massimino when he asked me about creatine. Greg is 38, owns a gym in Tampa, has been in the fitness industry his entire adult life, and had avoided creatine for years specifically because of the hair loss concern. He has a full head of hair, no family history of early-onset male pattern baldness, and was leaving performance on the table avoiding a supplement that would genuinely help him.

I walked him through the mechanism. We agreed to a 12-week trial with subjective monitoring for any scalp changes. Sixteen weeks later — no changes. Strength increased. Body composition improved. He texted me at the end of month three: “I wasted years avoiding this because of internet fitness content.”

Greg’s case is representative. The men most likely to make a creatine-hair loss connection and act on it are often the men for whom it’s least relevant.

When It Is Worth Thinking About

Bobby McAllister is the other side of this. Bobby came to me at 41 in the aftermath of finasteride use — he’d taken 1mg daily from 32 to 38, experienced post-finasteride syndrome symptoms that persisted for three years post-cessation, and was still rebuilding his androgenic function when I started working with him. DHT was at 19 ng/dL — low end of reference range, reflective of his prolonged 5-AR blockade history.

Counterintuitively, for Bobby, the creatine-DHT connection was a reason TO consider creatine, not to avoid it. He was trying to rebuild DHT production. An intervention that modestly upregulates 5-AR activity was directionally supportive of his recovery goal. We added creatine at month four of his protocol, monitored DHT quarterly, and saw his levels move from 19 to 31 ng/dL over six months — a meaningful improvement for a man who’d spent six years suppressing the enzyme responsible for that conversion.

Bobby’s case illustrates the contextual nature of what creatine’s DHT effect means: for men trying to support androgenic function, it’s a minor positive. For men with significant genetic hair loss risk who are deeply concerned about acceleration, it’s a reasonable thing to think about — though not necessarily to act on by avoiding creatine entirely. The risk-benefit math for most men still comes out strongly in favor of the supplement.

What the Cognitive Benefits Tell Us

Creatine’s cognitive benefits — improved working memory, reduced mental fatigue, faster processing in sleep-deprived states — are increasingly documented. The mechanism there is straightforward: the brain is an ATP-hungry organ, and phosphocreatine availability supports neurological energy metabolism.

But DHT also has neurological activity. DHT is a (neurosteroid — a steroid hormone synthesized in the brain or acting directly on neurological tissue, with effects on mood, cognition, and neuroplasticity) neurosteroid. It acts on GABA receptors, influences serotonin signaling, and has documented effects on mood and cognitive function in men. The subjective “mental sharpness” that many creatine users report may be a combination of two separate mechanisms: creatine’s direct ATP support and the mild neurological effect of marginally elevated DHT.

I don’t over-index on this distinction in practice — creatine works for cognition, the mechanism is probably mostly the ATP pathway — but it’s worth knowing that DHT is not purely a peripheral androgen. Its role in the brain is real, which is part of why post-finasteride syndrome produces neurological and mood effects in affected men. The brain has androgen receptors too.

Cameron’s Protocol and What the Bloodwork Showed

Cameron Falk is 25, a junior engineer in Phoenix, and was my fastest-responding client across the board. When I restructured his training from six days to four and pushed his protein adequacy and sleep, his T went from 520 to 740 in eleven weeks. We hadn’t touched creatine yet.

At month four, after his primary variables were settled, I added creatine monohydrate at 5g daily. His DHT at baseline had been 48 ng/dL. Eight weeks after adding creatine, it was at 62 ng/dL. His strength numbers continued improving. Body composition improved further. No subjective hair changes — he’s 25 with a full head of hair and no family history of early male pattern baldness.

Cameron’s bloodwork reflects what I’d predict for a young man with a working androgenic system: the creatine DHT effect manifested cleanly, and in his case it was an additional androgenic support on top of an already-improving hormonal environment.

For men in their 40s like Manny Ortega, the picture is more nuanced. Manny asked me specifically about prostate health — he’d read that higher DHT was associated with prostate issues. The evidence on DHT and prostate cancer risk is genuinely complicated, and I don’t present myself as an oncologist. What I can say is that the evidence connecting supplemental creatine, via modest DHT elevation, to prostate cancer risk is essentially nonexistent. The finasteride studies that reduced prostate cancer risk by blocking DHT were done in men with existing elevated prostate risk, at drug-level 5-AR blockade. Creatine is a different order of magnitude of DHT modulation. For Manny, who had no prostate symptoms and normal PSA, creatine wasn’t a prostate concern. It was a muscle and recovery tool.

The Practical Protocol

My recommendations haven’t changed from what the evidence supports. Creatine monohydrate, 3-5g daily. No loading phase needed — loading does saturate muscle stores faster, but the difference is a few weeks and the GI discomfort of 20g daily during the loading phase isn’t worth it for most people. Steady daily dosing at 3-5g reaches the same saturation over 4-6 weeks without the hassle.

Form: creatine monohydrate is the form with by far the most evidence and the lowest cost. Creatine HCl, buffered creatine, and other forms are marketed with claims about superior absorption and reduced water retention. The evidence for these claims over monohydrate is thin. I use monohydrate with clients. I haven’t found a reason to change that.

Timing: doesn’t matter much. Some evidence suggests taking it post-workout may have a small advantage in terms of muscle saturation during the recovery window. In practice, the easiest time you’ll remember to take it is the right time. Consistency matters more than timing precision.

This sits firmly in the S-tier on the supplement tier list — alongside vitamin D3, magnesium glycinate, and zinc when deficient. These are the supplements where the evidence is so consistent across decades of research and my own client tracking that I’d recommend them to almost anyone without qualification. The DHT nuance is worth understanding. It shouldn’t change the recommendation for the vast majority of men who would benefit from creatine.

Creatine is one of the few supplements the Anabolic Alchemy program includes without meaningful caveats. Add the DHT context to your understanding. Let the generational androgenic decline piece — why men’s physical phenotype has become less androgenic over time — frame why 5-alpha-reductase support matters. And take the 3-5g.

I will try to keep adding to the DHT knowledge-base on the website as the evidence evolves. For now, the creatine picture is clear enough: it works, the DHT finding is real but contextual, and the men avoiding it over hair loss concerns are almost always men for whom it wouldn’t matter anyway.
