The public register of Peptide Suppliers Association (PSA) members — suppliers who have committed to the PSA's evidence and disclosure standards. A professional trade register, not a consumer catalogue. Written for prescribers, industry professionals, and PepiScreen customers working with a peptide-literate clinician.
This directory does not rate suppliers. It lists company details, regions and product ranges only. PepiScreen does not publish assessments of named suppliers on this website. Certificate analysis — purity, batch traceability, laboratory checks and fraud indicators — is delivered privately in the PepiScreen app to the customer who requests it. Suppliers: update your listing.
