Fluoxymesterone vs Trenbolone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Fluoxymesterone | Trenbolone | |
|---|---|---|
| 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. | Trenbolone is a potent injectable anabolic-androgenic steroid — never a peptide — with no human efficacy trials, an FDA-approved use only as a cattle growth-promoting implant, and serious androgenic, cardiovascular, and hormonal risks. |

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…
Trenbolone
Trenbolone is one of the strongest anabolic-androgenic steroids around — and also one of the least studied in people. It is not a peptide and not a SARM (a different class of muscle-building drug). It's a true steroid, chemically related to another steroid called nandrolone. Nobody ever ran proper…
