The Claim

Creatine supplementation increases the conversion rate of testosterone to dihydrotestosterone (DHT), as evidenced by a sustained 22% elevation in the DHT-to-testosterone ratio without a change in total testosterone, indicating enhanced 5α-reductase activity in healthy young male athletes.

How it works
1 study reviewed
In plain English

Creatine supplementation increases the ratio of dihydrotestosterone to testosterone in healthy young male athletes, without changing total testosterone levels, indicating greater activity of the enzyme that converts testosterone to dihydrotestosterone.

See the scientific wording

Creatine supplementation increases the conversion rate of testosterone to dihydrotestosterone (DHT), as inferred from a sustained 22% elevation in the DHT:T ratio without a change in total testosterone, suggesting enhanced 5α-reductase activity in healthy young male athletes.

Why this might work

Creatine increases the activity of an enzyme that turns testosterone into a stronger hormone called dihydrotestosterone, leading to more of this hormone in the blood without changing the amount of testosterone.

  1. Study: Three Weeks of Creatine Monohydrate Supplementation Affects Dihydrotestosterone to Testosterone Ratio in College-Aged Rugby Players

    This study found that when young athletes took creatine, their body made more of a stronger hormone called DHT, even though the main hormone (testosterone) didn’t change. This means creatine might be helping the body turn testosterone into DHT more efficiently.
