Established coverage: 5+ tracked products. Limited coverage: 1–4. Verified testing means at least one tracked product has verified independent evidence or recognised certification. “All product testing reviewed” requires approved evidence reviews for every tracked product; it does not mean every product is independently tested. Suppliers without products currently shown are omitted.
Why supplier transparency matters
How we score research peptides →Company transparency
Know which registered company is selling the vials, where it is based and how to contact it.
Testing evidence
A supplier saying its products are tested differs from a published laboratory report for the exact vial. Evidence can vary between products.
Tracked product quality
Compare the products in our analysis. Affiliate relationships never affect our scores.
