California Peptide Club — Peptide Topology

What you're looking at

An interactive topology of the peptides being discussed in 2026. Each colored island is a category. Each vial is one peptide — click any vial to open a profile.

Sources

Alec Tatem defined the four scientific groupings used here (GH/IGF-1, Tissue Repair, Longevity/Nootropic, Immune/GU/α-MSH). The fifth class — GLP-1 / Metabolic — is a modern carve-out. Per-peptide content is drawn from Tatem, Dr. Ashley Froese, the Huberman Lab episode with Dr. Abud Bakri (Peptides: The Science, Uses & Safety), transcript notes, and clinical references. See the Foundations & Frameworks section of the Pedia for the conceptual background.

Tier

S FDA-approved or Tatem's "must-have"
A Strong evidence
B Promising
C Emerging / mostly anecdotal
D Skeptical
F Likely doesn't work

Symbols & scores

↻ Commonly cycled (on/off)
Vial fill height = strength of human research
Scores 1–10. Empty bars = no transcript-backed data; we don't guess.
