Mesterolone vs Nandrolone
Both are anabolic steroid compounds. Here's how they line up on the evidence — graded the same way.
| Mesterolone | Nandrolone | |
|---|---|---|
| Evidence | 1/10 | 8/10 |
| Class | Anabolic steroid | Anabolic steroid |
| Summary | Mesterolone is an oral, DHT-derived anabolic-androgenic steroid once sold abroad for male hypogonadism and idiopathic infertility. Controlled human trials for its two historic uses (fertility, mood) are negative or unconvincing, and its performance 'anti-estrogen' reputation has no strong human evidence. | Nandrolone is an injectable anabolic-androgenic steroid (not a peptide) with high-quality trial evidence that it builds lean mass in catabolic illness, but weaker evidence for strength or functional gains and real androgenic, hormonal, and cardiovascular risks. |

Mesterolone
Mesterolone, almost always sold under the brand name Proviron, is a man-made oral steroid. More precisely, it's an anabolic-androgenic steroid (AAS) — a synthetic relative of the male hormone dihydrotestosterone (DHT). It's an androgen (a male-hormone-type drug), not a peptide and not a SARM.…
Nandrolone
Nandrolone, best known by the brand name Deca-Durabolin, is a man-made anabolic-androgenic steroid (AAS — a drug that builds muscle and acts like testosterone). Chemically it's 19-nortestosterone, a close cousin of testosterone. It is not a peptide and not a SARM. There's real, solid human research…
