About
Numbers first.
Choosing a research peptide shop usually means trusting marketing copy. We’d rather lay out what each shop actually publishes — and show the gaps.
We score 45 shops on 5 criteria — purity & testing, transparency, price & value, shipping and support — and combine them with fixed, published weights. Scores are editorial estimates from each shop’s public information; every shop page shows the inputs and a spec sheet where unpublished facts are marked with a dash.
How we make money
Some of the listed shops are affiliate partners: we earn a commission when you buy through our links, and this can influence their placement. They also provide the 10 coupon codes on this site. Scores of every other shop come from public information. The full rules are on our methodology page; shop owners can apply on For shops.
What we don’t do
We don’t invent facts, ratings or reviews. We don’t give dosing, usage or medical advice, and we don’t endorse any product for human use — the shops listed sell for laboratory research only.
