Boldenone vs Fluoxymesterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Boldenone | Fluoxymesterone | |
|---|---|---|
| Evidence | Animal only | Preliminary human |
| 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. |
