EDITORIAL NOTE / 001

A reference, not a sales pitch.

The peptide research landscape is crowded with claims. This Codex is designed as a navigable reference: study context, mechanisms, and source trails presented with attention to what the record does—and does not—establish.

Use each guide as a starting point for reviewing the underlying literature and its limitations.
