How We Work
Every claim on this site is sourced to authoritative sources like PubMed, FDA.gov, or ClinicalTrials.gov with links, not footnotes. We’re a reporting site, not a storefront: we don’t sell peptides. If we ever link to a vendor or affiliate, we say so clearly. We’re currently building out credentialed medical review for every article that touches dosing or safety.
