TB-500 — Reta PeptideCertificate 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.
Dose vs label No quantity measurement on this report.
Evidence Artifact captured Trust: low Blend
AI summary Source unclear

This COA's source attribution is incomplete, derived from a Janoshik blend test for TB-500 from www.reta-peptide.com. While the test date is recent (3-6 months), specific purity, test method, and endotoxin status are unknown. The tested quantity was 5.38mg, but the labeled quantity is not available for comparison. Customers should treat this as one data point and cross-reference with other COAs for confirmation.
