Fluoxymesterone vs Testosterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Fluoxymesterone | Testosterone | |
|---|---|---|
| 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. | Testosterone is the principal human androgen and the prototypical anabolic-androgenic steroid (AAS) — not a peptide — with strong, reproducible human evidence for dose-dependent muscle and strength gains, FDA approval only for confirmed hypogonadism, Schedule III control, and real cardiovascular, hematologic, and hormonal safety signals. |

Fluoxymesterone
Fluoxymesterone, sold for decades under the brand name Halotestin, is a synthetic anabolic-androgenic steroid (AAS). It is an orally active, 17α-methylated derivative of testosterone — a steroid, not a peptide and not a SARM. It has a real but now largely historical FDA-approved medical pedigree,…
Testosterone
Testosterone is the body's principal androgen and the molecule from which the entire class of anabolic-androgenic steroids (AAS) is derived. It is a steroid, not a peptide. It has decades of FDA-approved medical use as replacement therapy for men with confirmed hypogonadism, and the human evidence…
