Semaglutide — GYCCertificate 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. It indicates a semaglutide quantity of 5.28mg against a 5mg label, representing a 5.6% deviation. Purity and endotoxin data are not available, and the test is stale (over 1 year old). Customers should treat this as one data point and not as confirmation.

Watch out for
  • unknown source
  • no purity test
  • no endotoxin test
