Drag-drop your COAs

Same upload flow labs use — single PDF / JPG / PNG or bulk ZIP up to 500 files. Claude auto-extracts peptide, lot, purity, endotoxin, sterility. Live on your vendor page in seconds.

Lab cross-reference

We content-hash match every vendor upload to its issuing lab. If the lab uploaded the same file, your record auto-stamps "Confirmed: Lab + Vendor" — the strongest authenticity signal in our corpus.

Email-on-domain

We email a one-time link to a mailbox on your domain (e.g., [email protected]). Whoever clicks the link claims the profile. No DNS work required.

Free, revoke any time

No paid tier on the vendor side. Claiming, uploading, publishing, revoking — all free. Pull any COA from public view with one click; forensic record stays.
