Understanding peptides,
grounded in the research.
A clean, citation-first library covering the peptides most discussed in contemporary science — what they are, how they work, and what the literature actually says about them.

Popular peptides
BPC-157
Research compoundHealing & Recovery
A stable 15-amino-acid peptide fragment derived from a protein in human gastric juice, widely studied in preclinical models for tissue protection and repair across gut, tendon, muscle, and vascular tissue.
Ipamorelin
Research compoundGrowth Hormone
A synthetic pentapeptide that gently nudges the pituitary to release its own growth hormone — studied for clean, selective GH pulses without the cortisol or prolactin effects of earlier secretagogues.
Retatrutide
InvestigationalMetabolic
An investigational Eli Lilly triple agonist at the GLP-1, GIP, and glucagon receptors, currently in Phase 3 development with some of the largest weight-loss effect sizes reported in clinical pharmacotherapy.

How to read peptide research
A working field guide for critically reading the scientific literature on peptides — what the study type tells you, what "statistically significant" doesn't tell you, and how to spot the signals that a finding is stronger than it looks.
