New in 1.1: a free COA Authenticity Checker. Paste a lab report link or photo for an instant read. Plus a faster redesign, smarter AI, and more vendors. Research only.
PeptidePrices is an independent price-comparison tool for research peptides.
WHAT YOU CAN DO
• Compare prices across 36 verified vendors for 148 research compounds
• See COA verification status, third-party lab names, and quality ratings on every vendor
• Check a COA's completeness and consistency with the built-in COA Authenticity Checker (paste a link or upload a photo or PDF)
• Filter vendors by shipping coverage (US, Canada, international)
• Track price history and set alerts when watched compounds drop
• Use the AI research assistant to surface relevant compounds for a research area, with live vendor pricing
• Read independent vendor reviews aggregated from public platforms
WHY PEPTIDEPRICES
We are independent. We are not a peptide vendor. No sponsorship influences our vendor rankings. Affiliate commissions help fund the site but do not change quality scores. Our full methodology is published at peptideprices.net/trust.
Quality scores use a transparent weighted rubric:
• 40% — COA practices (named lab, batch linkage, public availability)
• 20% — Community reputation
• 20% — Transparency (address, ownership, contact)
• 20% — Operations (shipping, customer service, payment flexibility)
Prices are normalized to a standard cost-per-milligram figure so comparisons are apples-to-apples. Every listing shows when it was last verified.
RESEARCH USE ONLY
Compounds referenced in this app are research materials. Not for human consumption. Not medical advice. This app does not diagnose, treat, or provide patient instructions. Always consult a licensed professional. A persistent research-use reminder appears on every screen, and a 21+ confirmation is required on first launch.
PRIVACY
This native app loads no third-party tracking or advertising SDKs. Account data (email, name) is used only to provide the service. We do not track you across other apps or websites.
