Fluoxymesterone vs Testosterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Fluoxymesterone | Testosterone | |
|---|---|---|
| Evidence | 8/10 | 10/10 |
| 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. | 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 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…
Testosterone
Testosterone is the body's main androgen (the main male sex hormone), and it's the molecule the whole family of anabolic-androgenic steroids (AAS) is built from. It's a steroid, not a peptide. Doctors have prescribed it for decades as replacement therapy for men whose bodies don't make enough — a…
