BPC-157 + TB-500 — Jett LabsCertificate of Analysis · Independent third-party lab result

Purity Blend Blend tests measure quantity per component, not overall purity — a purity assay for a multi-peptide sample needs separate chromatographic runs.

This COA was extracted from a community forum / Discord channel. The original poster claimed a lab tested Jett Labs' BPC-157 + Thymosin Beta-4 blend, reporting 97.411% purity via HPLC with UV Detection Coupled with Mass Spectrometry. The blend components were reported as 10.91mg for BPC-157 (10mg label) and 10.16mg for Thymosin Beta-4 (10mg label). The image has passed through at least one re-share, so the lab's signature is not directly verifiable, creating a chain-of-custody gap. This should be treated as community signal, not confirmation.

Watch out for
  • chain-of-custody gap
  • unknown lab
  • no endotoxin test
