Peptides vs SARMs: what's the difference?
They get lumped together and they shouldn't be. Different molecules, different mechanisms, different legal lanes.

Peptides and SARMs get lumped together in the same forums, but they're chemically and mechanistically different, and they sit in different legal lanes.
SARMs (selective androgen receptor modulators) are small non-peptide molecules that act on the androgen receptor — the same receptor testosterone uses. Peptides are amino-acid chains that act on a huge variety of receptors and pathways. The only real thing they share is a grey-market and a reputation.
Why the distinction matters
- Different mechanisms mean different risks — you can't reason about one from the other.
- Different legal treatment — both are typically research-only for human use, but they're regulated under different logic.
- Different evidence bases — conflating them imports the hype from one into the other.
