About Peptifact

Peptifact exists because the research-peptide market runs on claims nobody checks. Vendors publish purity numbers with nothing behind them; buyers gamble on checkout pages.

We do the checking: real orders placed anonymously, certificates cross-checked against independent analysis, shipping and support measured — the same 14-point protocol for every vendor, documented so you can audit our work.

Rankings on this site follow our published testing criteria. They are never sold, and no vendor can pay to change a score.

Peptifact is operated by Sherdas LLC. Contact: contact page.
