The Look Set is three Peptide Knowledge field guides for the people asking about skin, hair, libido and tanning: the cosmetic peptides in every serum, the hair compounds, and the two most-hyped injectables in the space.

What you get:

• Field Guide 1: Start Here (the primer and the evidence-grading system)
• Field Guide 7: Libido & Tanning
• Field Guide 8: Skin & Hair

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. Screen and print editions, instant download.

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.

Want all eight guides? The Complete Set is $57.
