Fluoxymesterone vs Methandrostenolone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Fluoxymesterone | Methandrostenolone | |
|---|---|---|
| Evidence | Preliminary human | Strong human |
| 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. | An oral 17α-alkylated anabolic-androgenic steroid (not a peptide) with real but modest controlled-trial evidence for gains in body weight and lean mass; it is a Schedule III controlled substance with no current US medical use and well-documented liver, cardiovascular, and hormonal harms. |
