How to read this library
Peptide topics are framed as mechanisms, model systems, or clinical contexts, not self-use guidance.
Cards separate biological plausibility from human outcomes, internet lore, and unsupported claims.
This site avoids dosing, sourcing, injury treatment, weight-loss promises, and medical instructions.
