Safety-aware guides

Peptide pages explain legal status, research-only language, FDA context, and the difference between math and medical advice.

Important safety note

This page is a math and education tool. It does not tell anyone what peptide to use, how much to use, how often to use it, how to inject it, or where to buy it. Use values from a prescription, product label, or research protocol and verify decisions with a qualified professional.
