About Peptide Source Book

Peptide Source Book is an independent reference for peptides. For each molecule we bring together the research evidence, graded by study design, and the regulatory status from the FDA, EU and WADA, with every claim linked to a primary document. We built it because the useful information on peptides is scattered across PubMed abstracts, regulatory dockets and forum threads, while the easy-to-find content is mostly marketing or hype. Our job is to show what is actually proven, what is only preliminary, and what the law says, clearly enough that you can open the source and check it yourself. We do not sell peptides and we do not rank vendors. Nothing here is medical advice.
