Peptide library

24 profiles written in plain English. What each peptide is, how it works, the dose ranges research papers cite, and the honest state of the evidence.

  • BPC-157 : The most studied repair peptide, used in research on tendon, muscle, and gut healing.
  • TB-500 : A systemic repair peptide studied for cell migration and scar tissue.
  • Semaglutide : A long-acting GLP-1 agonist with large human trials behind it.
  • Tirzepatide : A dual GIP and GLP-1 agonist with the strongest published weight results to date.
  • Retatrutide : An investigational triple agonist still in clinical trials, not approved anywhere.
  • Ipamorelin : The gentlest growth hormone secretagogue, usually the first one people research.
  • CJC-1295 (no DAC) : A GHRH analogue that amplifies each growth hormone pulse.
