PepEvolutionThe peptide provider directory
scored by data.
400+ clinics, telehealth platforms, and compounding pharmacies. Independently scored by data. Not a paid ranking.
The PepScore™ Grade Board
9 compounds graded 0–100 across four buyer-relevant axes — Evidence, Sourcing & COA, Safety, and Practicality — banded A+ to F. We grade the decision to buy, not just the molecule. Sort it, then open any compound for the full axis breakdown and its best-sourced verified vendor.

Why PepEvolution is different
Data-driven scoring
Every provider is ranked by an objective 100-point score: verification status (35%), ratings & reviews (25%), telehealth availability (20%), and peptide breadth (20%). No pay-to-play.
Independent and transparent
We map the full supply chain — from API manufacturers to US compounders to research vendors. Understand what you're actually buying and who made it.
Independent research
We earn commissions from some outbound links — clearly labeled. It never affects rankings or scores. The data is the data.
