Check a store domain

Paste the address of a peptide store. You get what named sources have said about it: the domain we list for a store, one a vendor or a named source says is not the vendor's, one whose catalog matches a listed store, a related business, a former address or a closed store, each with its source and date. We make no finding of our own, and "not on file" is not a verdict either way.

147 domains on file, as of Sep 26, 2026: the domain we list for every store on the board, plus domains that stores or named sources have said are theirs, are not theirs, match their catalog or once were theirs. Each entry carries its source.
