What vendors’ certificates document

For each listed offer, PeptideTech read the vendor’s newest certificate for that exact product and counted the core tests it prints (identity, purity, net content, endotoxin, sterility, heavy metals, multi-vial conformity). Checked Oct 7, 2026. The certificate filter above hides vendors with no qualifying offer; it is not a ranking or a quality score.

Vendor questions

Vendor profiles describe published testing claims, shipping, payment options and dated price sources. A COA reported label means the vendor says it publishes certificates; it does not establish independent batch verification. We do not publish unsupported numerical ratings. Price comparisons use matching packages, stock and source freshness.
How we verify prices

Automated price sources are scheduled daily; other sources are checked manually. Check the offer's last successful source timestamp. A code is shown when it is attached to an offer or affiliate link. The displayed price includes a discount only when that code is cart-verified and the discounted price is explicitly recorded; otherwise it is the vendor's listed price. Prices exclude shipping. Stock status is captured at the same time. Rankings are by displayed price only. PeptideTech earns a commission when you buy through a link; it never changes the order.
