The Claim

After 14 days of maintenance dosing at 5 g/day of creatine monohydrate, the DHT-to-testosterone ratio is elevated by 22% in young male athletes.

In plain English

In young male athletes taking 5 grams of creatine monohydrate daily for 14 days, the ratio of dihydrotestosterone to testosterone is 22% higher than before treatment.

See the scientific wording

The DHT-to-testosterone ratio remains elevated by 22% after 14 days of maintenance dosing (5 g/day) of creatine monohydrate, indicating that the hormonal effect persists beyond the initial loading phase in young male athletes.

Why this might work

Creatine increases the activity of an enzyme that converts testosterone into a stronger hormone called DHT, causing more DHT to build up relative to testosterone without changing the total amount of testosterone.

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

    The study found that when young athletes took creatine for three weeks—starting with a high dose and then lowering it—their body made more DHT than testosterone, and this difference stayed higher for two full weeks even after cutting the dose. So yes, the effect lasted.
