Fluoxymesterone vs Trenbolone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Fluoxymesterone | Trenbolone | |
|---|---|---|
| Evidence | Preliminary human | Animal only |
| 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 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,…
Trenbolone
Trenbolone is one of the most potent anabolic-androgenic steroids in circulation, but it is also one of the least studied in humans. It is not a peptide and not a SARM — it is a true steroid, a chemically modified relative of nandrolone. It was never carried through human anabolic trials, so…
