Peptides are fundamentally changing medicine. We publish the clearest, most current reference on what works, what’s promising, and what’s still hype, organized by goal and rated by evidence.
124 compounds · 12 goal categories · Updated weekly
Nothing on this site is ranked by how trendy it is. We classify each compound by where it sits in the evidence hierarchy, and show you why.
Every peptide is organized by what it actually does, not by trade name, not by marketing category. Pick a goal and start there.
Pulled from search volume, trial citations, and editorial picks. Each entry links to a full profile.
View all 124Semaglutide
Long-acting GLP-1 receptor agonist approved for type 2 diabetes and chronic weight management, with established cardiovascular benefit.
Tirzepatide
Dual GIP/GLP-1 receptor agonist producing greater average weight loss than semaglutide in head-to-head trials.
Retatrutide
Investigational triple agonist (GLP-1, GIP, glucagon) producing the largest weight loss seen in Phase II trials to date.

Synthetic fragment of thymosin beta-4 promoting actin regulation, cell migration, and tissue repair.
Ipamorelin
Selective ghrelin receptor agonist that releases GH without meaningfully raising cortisol or prolactin. The cleanest GHRP.

Step 01
Pick a goal: fat loss, healing, cognition, longevity. We group peptides by what they actually do, not by trade name.
Step 02
Every peptide has a detailed page: mechanism, dosing protocol, practical notes. Both standard and women's protocols where they differ.
Step 03
Every compound is rated: established, clinical, preclinical, or experimental. The reasoning is always on the page.
The US peptide supply chain changed materially between late 2023 and early 2026: 14+ peptides restricted from compounding, two of the largest research vendors shut down, and 55 FDA warning letters in September 2025 alone.
Our directory maps every supplier with their credentials and their red flags on the same card. Nothing is recommended. Everything is cross-verifiable.
