Reviews
4.1★★★★☆ · 27 reviews on Trustpilot
Read it critically. A Trustpilot score measures whether parcels turn up and support replies, not whether the vial contains what the label says. A vendor can have hundreds of happy delivery reviews and still show you a borrowed or fake certificate; the two are unrelated. Also watch for a burst of near-identical 5-star reviews in a short window, the signature of bought reviews.
🚩 Bank only, bank transfer / crypto only, so if it never ships there is no chargeback to get your money back.

The bottom line. Simplypeptides earns a place on the independently-tested list because it pays an independent lab (Janoshik) to test its own stock in its own name, and lets you verify it. That is the standard.
