Fluoxymesterone vs Methasterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Fluoxymesterone | Methasterone | |
|---|---|---|
| Evidence | 8/10 | 3/10 |
| Class | Anabolic steroid | Anabolic steroid |
| Summary | Fluoxymesterone is an oral 17α-alkylated anabolic-androgenic steroid (not a peptide), once FDA-approved for hypogonadism and breast-cancer palliation but now largely obsolete. Its strongest, best-documented human data concern liver injury rather than benefit, and non-medical use is illegal and banned in sport. | 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. |

Fluoxymesterone
Fluoxymesterone, sold for decades under the brand name Halotestin, is a man-made anabolic-androgenic steroid (AAS) — a lab-made cousin of testosterone. You take it as a pill, and it's built from testosterone with a chemical tweak (called 17α-methylation) that lets it survive being swallowed. It's a…
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…
