Process
How It Works
We Test
We independently source and verify every certificate of analysis against certified lab standards.
We Score
Our 12-metric, 5-pillar PVS algorithm — with HPLC purity as the #1 weighted factor — scores every vendor on data alone.
We Publish
Full rankings published openly with every metric — zero conflicts of interest, zero paid placements.
Our Platform
Data-Driven Verification
Lab report verification
Every Certificate of Analysis (CoA) is cross-checked against a third-party reference lab — purity, identity, contaminants.
Independent vendor score
A 12-metric score covering purity, shipping, customer service, and community sentiment. Updated daily.
Purity testing
HPLC and mass-spec data cross-referenced for identity and concentration accuracy.
Score history
Track how each vendor's quality and reputation has shifted over the past 12 months.
Verified buyer reviews
Reviews tied to a confirmed purchase, plus aggregated sentiment from public Reddit threads.
Zero paid placements
Vendors cannot pay to rank higher. Ever. Rankings are determined by data alone.

What the Community Says
“After getting burned twice by vendors with fake CoAs, PepAssure is the only place I check before ordering. The methodology is actually rigorous.”
u/ResearchChemBio
r/Peptides
“I'm a biochemist. The CoA verification criteria here are solid — they catch the same red flags I look for manually. Saves me hours of due diligence.”
u/peptide_phd
r/ResearchChemicals
“The vendor comparison tool alone is worth it. Side-by-side CoA counts, sentiment, and scores — everything I need in one place.”
