Mesterolone vs Methasterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Mesterolone | Methasterone | |
|---|---|---|
| Evidence | No credible evidence | Animal only |
| Class | Anabolic steroid | Anabolic steroid |
| Summary | Mesterolone is an oral, DHT-derived anabolic-androgenic steroid once sold abroad for male hypogonadism and idiopathic infertility. Controlled human trials for its two historic uses (fertility, mood) are negative or unconvincing, and its performance 'anti-estrogen' reputation has no strong human evidence. | Methasterone is an oral 17α-alkylated anabolic-androgenic steroid (a 17α-methyl version of drostanolone), never an approved medicine; its only robust human evidence is harm — severe cholestatic liver injury — not efficacy. |
