# Peptidology

> Peptidology is an independent research-use-only (RUO) education platform for peptide research. Since December 2024 it has published cited compound roundups, lab-literacy guides, and transparent vendor vetting scorecards — more than eighteen months of continuous editorial work. Content is written for laboratory researchers; it is not medical advice and includes no dosing or human-use instructions.

Peptidology does not sell peptides. Vendor scores use the same criteria for every listed source.
