Every lot screened for heavy metals, sterility, and endotoxins, not just purity.
Not for human or animal consumption, therapeutic, clinical, diagnostic, dietary, dosing, injection, ingestion, or administration use.
Almost any vendor can confirm a peptide is 99% pure. Far fewer screen for the heavy metals, endotoxins, and microbes a purity test never catches, and almost none let you call and verify your exact lot. We do all three.
