Each status is quoted from its source. A shop with no working website may still sell through messaging apps, which is a reason for more caution, not less.

Before you order BPC-157

  • Look at the shop's grade for BPC-157, not its average. Qing Li Peptide has the most BPC-157 tests (35); a shop with one or two tests has not shown it is consistent.
  • 69% of these vials were bought and sent in by customers; the rest were sent by Finnrick or by the shop itself. Results from vials a shop chose to send are the weakest evidence.
  • 10 labs tested them, mostly Krause Analytical and BTLabs. Ask for the certificate for your batch and check it on the lab's own site.
  • Run the vendor checklist before paying, and read how the grades work.
