Boldenone vs Methasterone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Boldenone | Methasterone | |
|---|---|---|
| Evidence | Animal only | Animal only |
| 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. | Methasterone is an oral 17α-alkylated anabolic-androgenic steroid (a 17α-methyl version of drostanolone), never an approved medicine; its only robust human evidence is harm — severe cholestatic liver injury — not efficacy. |
