Field Guide 1: Start Here is the free primer for the Peptide Knowledge series. It teaches the one skill every other guide depends on: how to read a peptide claim and grade it before you believe it.

Inside: how peptides are regulated in plain English, what FDA-approved, compounded, research-only and grey-market actually mean, the evidence grading we use across the series (Solid, Partial, Empty, Dashed), how to check a claim yourself in ten minutes, the questions to ask any seller or clinic, and a map of the seven topic guides so you know which one you need.

Screen edition PDF, instant download. Educational only. We do not sell, recommend, dose or source any compound, and nothing here is medical advice. Every claim in the series carries a dated, numbered source. Evidence current as of 4 Oct 2026.

When you want the topic guides, pick a $27 set (Body, Mind and Longevity, or Look) or get all eight in The Complete Set.
