TL;DR — Key Takeaways

• No, creatine does not meaningfully increase testosterone. A meta-analysis found no significant effect.
• It doesn’t raise free testosterone either.
• The “creatine boosts DHT / causes hair loss” idea came from one 2009 study, recent trials found no significant DHT or hair effect.
• Creatine’s proven benefits (strength, power, muscle) come from energy (ATP) production, not hormones.
• It’s one of the safest, most effective supplements ju, t not a testosterone booster.

No, creatine doesn’t increase testosterone. A meta-analysis found no significant effect on total or free testosterone. The old “creatine raises DHT and causes hair loss” idea came from one 2009 study, but recent trials found no significant DHT or hair effect. Creatine’s proven benefits, strength, power, muscle, come from energy production, not hormones. It’s safe and effective, just not a testosterone booster.

Creatine is the most-researched sports supplement there is, so does it move testosterone? Here’s what the actual evidence says (and why the hair-loss fear is overblown). (Part of our guide on how to increase testosterone naturally; for the overview, our complete TRT guide.)

Does Creatine Increase Testosterone?

No, not meaningfully. Despite the gym-lore, the research is clear: creatine does not significantly raise testosterone. Unlike better-evidenced options like ashwagandha, creatine works through a completely different mechanism, energy, not hormones.

Key fact: A meta-analysis found creatine has no significant effect on testosterone and recent trials found no effect on DHT or hair loss either. Creatine works through energy, not hormones.

What the Studies Show

The evidence is consistent:

• A systematic review and meta-analysis (Delpino, 2022) found no significant effect of creatine on total testosterone.
• Across studies, 10 of 12 showed no testosterone change; the two exceptions were tiny, physiologically insignificant rises. Free testosterone was measured in five studies, no increases.
• So creatine simply isn’t a testosterone booster, in deficient or healthy men.

What About DHT and Hair Loss?

This is the myth worth killing. The “creatine causes hair loss” fear traces to one 2009 rugby-players study that found a higher DHT-to-testosterone ratio (DHT, not testosterone) after creatine. But:

• Recent controlled trials, including a 12-week RCT, found no significant difference in DHT, DHT:testosterone ratio, or hair growth between creatine and placebo.
• Current evidence does not show creatine consistently raises DHT or causes baldness.

So for most men, creatine is not a hair-loss risk, reassuring context alongside the real drivers in TRT and hair loss.

How Creatine Builds Muscle (Without Testosterone)

Creatine works by regenerating ATP (your cells’ energy currency) via phosphocreatine, letting you train harder, lift more, and recover better. That drives strength, power, and muscle gains directly, no hormonal boost required. It’s why creatine helps whether your testosterone is high or low, and why it pairs well with any TRT workout plan or the muscle goals behind will 100mg of testosterone a week build muscle.

Is Creatine Safe?

Yes, it’s one of the safest, most studied supplements. Standard dosing is 3–5 g/day of creatine monohydrate (an optional “loading” phase of ~20 g/day for a week isn’t required). Common myths (kidney damage, dehydration, hair loss) aren’t supported in healthy people. Those with kidney disease should check with a doctor first. It’s a staple among the best supplements to take while on TRT — for performance, not hormones.

Should You Take Creatine for Testosterone?

For testosterone specifically, no, it won’t help. But for strength, muscle, power, and even cognition, it’s excellent and worth taking. If your goal is actually raising low testosterone, focus on the proven levers in how to increase testosterone naturally, and if you have low testosterone symptoms, test your levels and see whether TRT is right for you.

conclusion

Does creatine increase testosterone? No, a meta-analysis and most studies show no significant effect on total or free testosterone. The DHT/hair-loss worry came from a single 2009 study and hasn’t held up in recent controlled trials. Creatine is a fantastic, safe supplement for strength, power, and muscle, but it builds those through energy production, not hormones. Take it for performance, not testosterone.

Frequently Asked Questions

Does creatine increase testosterone?

No, not meaningfully. A meta-analysis found no significant effect of creatine on total testosterone, and most studies show no change in total or free testosterone. Creatine improves strength and muscle through energy production, not by raising hormones.

Does creatine increase DHT?

Probably not, in most people. The idea comes from one 2009 study showing a higher DHT-to-testosterone ratio, but recent controlled trials, including a 12-week RCT, found no significant difference in DHT or the DHT ratio versus placebo. The evidence doesn’t support consistent DHT elevation.

Does creatine cause hair loss?

Current evidence says no. A 12-week randomized controlled trial found no significant differences in DHT or hair-growth measures between creatine and placebo. The hair-loss fear stems from one older study on DHT ratio, which recent research hasn’t confirmed.

How does creatine build muscle if not through testosterone?

Creatine regenerates ATP (cellular energy) via phosphocreatine, letting you train harder, lift heavier, and recover better. This drives strength, power, and muscle gains directly, independent of hormones — which is why it works regardless of your testosterone level.

Is creatine safe?

Yes, it’s one of the safest and most researched supplements. Standard dosing is 3–5 g/day of creatine monohydrate. Myths like kidney damage, dehydration, and hair loss aren’t supported in healthy people, though those with kidney disease should consult a doctor first.

Should you take creatine for testosterone?

Not for testosterone, it won’t raise it. But for strength, muscle, power, and cognition, creatine is excellent and worth taking. If your goal is raising low testosterone, focus on proven levers like sleep, fat loss, and training, and test your levels if you have symptoms.
