Peptide hubs.

Category-level reference guides — deep dives into peptide classes, mechanisms, and clinical context.

8 editorial reference pages that sit above the 156-profile directory. Each hub covers one therapeutic class — mechanism, every PeptaHub profile in the category, a comparison table, a safety section, an evidence-stratified editorial stance, and an FAQ. Use these to orient before drilling into individual profiles.

HOW THESE DIFFER FROM PROFILES

Hubs vs profiles

Individual peptide profiles cover a single compound in depth — mechanism, dosing, side effects, legal status. Hubs sit one level up and cover an entire therapeutic class. If you know the compound you want, go to the profile. If you want to orient yourself on the class — which compounds exist, how they compare, what the evidence landscape looks like — start at a hub.

Every hub cross-links to the individual profiles it references. Every profile in a hub's scope links back to its parent hub. Together they form the editorial spine of PeptaHub's reference coverage.
