Boldenone vs Fluoxymesterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Boldenone | Fluoxymesterone | |
|---|---|---|
| Evidence | 3/10 | 8/10 |
| Class | Anabolic steroid | Anabolic steroid |
| Summary | Boldenone is an injectable anabolic-androgenic steroid (a synthetic derivative of testosterone), not a peptide. Its only sanctioned use today is veterinary; there is no modern human clinical evidence supporting its physique or performance claims. | 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. |

It comes as a long-acting injectable (a form called the undecylenate ester, which slows how fast the…

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…
