M-Peptide Science
M-Peptide Science provides certificates for 87% of batches, nearly double the site median, though community members have commissioned 29 group tests—above the site median of 14—suggesting customers are independently verifying batches beyond what the vendor documents. Fill weight runs consistently high at a median of 110.1% of label. One batch (M2P0S27-6J, a BPC-157 & TB-500 blend) was flagged, and two direct problem reports exist against batches in the tracked set, with limited detail available on resolution.
Written from the batch and test records on this page. Every certificate counted here was commissioned by the vendor — no independent test has been submitted to the site. Updated 2026-09-03.
