Vendors love to wave a "Certificate of Analysis" at you. Many are self-made, borrowed from a Chinese supplier, or simply invented. Upload the COA a shop gave you (image or PDF) and get an instant, honest read on what it actually proves, cross-checked against everything The Peptide Watch knows.
One honest caveat: this reads the document, it tells you whether the certificate itself is genuine, self-made, borrowed or fabricated. It cannot tell you whether the vial you receive matches it; no document, and no website, can prove that without independently testing the exact unit. It's here to catch fakes and reduce uncertainty, not to guarantee a product.
This is an AI-assisted assessment to help you think, not a definitive lab result, it reads only the image you upload. Always verify a Janoshik report yourself at verify.janoshik.com. The Peptide Watch sells no peptides, takes no vendor money, and isn't affiliated with any shop. Research use only.
