About

PeptideCompare is a free, independent price comparison for research peptides.

Prices: 18,000+ listings collected from 220+ vendor websites, normalised to price per mg, with shipping, minimum orders and public coupons.
Evidence: independent lab test results, 4,900+ vendor-published COAs (checked against the issuing lab's own records where possible) and a 0-100 metascore that pools every source.
Safety: vendors caught publishing fake or doctored lab reports are banned and their listings removed.
Tools: a shopping planner that finds the cheapest way to buy a stack, a reconstitution calculator, vial label maker, research summaries and a clinical-trials tracker.

No account needed. Some vendor links are disclosed affiliate links; they never affect prices, rankings or plans.

Competitors: Finnrick

From the founder

Who it's for

“People researching peptides who want to compare vendor prices per mg alongside independent lab test results before they buy.”

Why I built it

“We are a small independent team. Prices and lab reports were scattered across hundreds of vendor sites, so we built one free place that ranks listings by price per mg and puts the evidence next to each price. No signup, and rankings can't be bought.”

— The founder of PeptideCompare
