The Complete Set is all eight Peptide Knowledge field guides: an independent, evidence-led hearing for the 59 peptides everyone is talking about, from the GLP-1 medicines to the research names sold online.

What you get:

• Field Guide 1: Start Here (the primer and the evidence-grading system)
• Field Guide 2: Weight & Metabolism
• Field Guide 3: Recovery, Joints & Bones
• Field Guide 4: Growth Hormone & Muscle
• Field Guide 5: Brain, Mood & Sleep
• Field Guide 6: Longevity & Immune
• Field Guide 7: Libido & Tanning
• Field Guide 8: Skin & Hair
• Screen editions and print editions (16 PDFs), plus the Stay-Current links file
• Updated editions as the evidence changes, included

Each guide gives every compound the same fair hearing: what the market says, what the labs show, what is FDA-approved versus compounded versus research-only, what sport testing says, and an honest evidence grade (Solid, Partial, Empty, Dashed) with a dated, numbered source behind every claim.

Educational only. We do not sell, recommend, dose or source any compound, and nothing here is medical advice. Evidence current as of 4 Oct 2026.
