CJC-1295 (mod GRF 1-29) — Peptide GurusCertificate 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

Source attribution for this COA is incomplete, derived from a Janoshik blend test. The quantity tested was 4.44mg against a 4mg label, showing an 11% deviation. Purity and endotoxin status are unknown, and the test is recent (3-6 months old). Customers should treat this as one data point, not as confirmation.

Watch out for
  • no purity test
  • no endotoxin test
  • quantity deviation (11%)
