Mesterolone vs Methasterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Mesterolone | Methasterone | |
|---|---|---|
| Evidence | 1/10 | 3/10 |
| 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. |

Mesterolone
Mesterolone, almost always sold under the brand name Proviron, is a man-made oral steroid. More precisely, it's an anabolic-androgenic steroid (AAS) — a synthetic relative of the male hormone dihydrotestosterone (DHT). It's an androgen (a male-hormone-type drug), not a peptide and not a SARM.…
Methasterone
Methasterone — most people know it by the designer-supplement name Superdrol, and chemists call it methyldrostanolone — is a man-made anabolic-androgenic steroid (AAS), not a peptide. It is an oral steroid built on a dihydrotestosterone backbone, with a chemical tweak called 17α-alkylation that…
