The Mind & Longevity Set is three Peptide Knowledge field guides for the people asking about focus, mood, sleep, aging and immunity: the nootropic peptides, the sleep and stress compounds, and the longevity and immune family that gets the biggest claims and the thinnest evidence.

What you get:

• Field Guide 1: Start Here (the primer and the evidence-grading system)
• Field Guide 5: Brain, Mood & Sleep
• Field Guide 6: Longevity & Immune

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.
