Can I trust a peptide vendor's own lab test results?

Treat a certificate a seller uploads to their own site as a claim until you can check it against the laboratory itself. Some laboratories in this market run a public verification portal where a batch or report code pulls up the original result independently of what the seller posted, which is a materially stronger form of proof than a PDF. Our laboratory profiles list which of the 21 labs we reviewed offer that kind of independent lookup.
