The Peptide Addict library is organized by compound. Each profile carries a visible scorecard across six dimensions and separates what is known, unknown, and overstated. New profiles are added on a weekly cadence.

Currently published

Coming soon

The full launch library includes canonical pages for:

  • GLP-1 class — semaglutide, tirzepatide, retatrutide
  • Recovery class — TB-500, GHK-Cu
  • Growth hormone secretagogues — CJC-1295, ipamorelin
  • Longevity class — MOTS-c, epitalon
  • Sexual health — PT-141
  • Cognitive class — semax, selank

Each profile is written using the Peptide Addict four-lens framework. See our methodology for the evaluation approach, and the Beginner's Guide for the foundational framing.

What a The Peptide Addict profile contains

Every profile includes:

  • Scorecard — evidence strength, human data depth, safety certainty, regulatory clarity, access complexity, and hype gap
  • What it is — plain-English description of the compound
  • Why people use it — honest account of the usage landscape
  • Mechanism in brief — what the biology suggests
  • Human evidence — what actually exists, not what's implied
  • Preclinical evidence — animal and in-vitro data with appropriate caveats
  • Safety and side effects — known, unknown, and what contamination implies for gray-market sourcing
  • Legal and access reality — where this compound sits in the US regulatory landscape
  • Hype vs reality — the gap, named directly
  • Key unanswered questions — what would change our view
  • Sources — what we read, what we relied on

Profiles are living documents. We update them as evidence emerges.
