Are research peptides third-party tested?
A research peptide is third-party tested only when that lot's certificate of analysis names an outside laboratory; a note that a certificate is available on request is not itself a posted test.
The catalog these notes link says certificates of analysis are available on request, and many product pages say a certificate is not posted yet. That is a request path, not a result. Until the sheet is in hand, identity, purity, method, and any outside lab are unknown.
What to read on the sheet is in What a certificate of analysis is for: identity, purity and method, form, and a lot number that matches the vial. If the laboratory named on the sheet is the seller's own bench, call it the seller's assay. Call it third-party only when a different laboratory is named.
Residue Notes does not treat "COA on request" as a pass, and it does not invent a testing lab. Ask for the lot document and read it. The compound pages, including BPC-157 and GLP-3R, point at listings, not at a substitute for that sheet.
