Certificates of Analysis (COAs)

Independent Testing Transparency

All peptides are sourced from manufacturers who specify a purity of ≥99% based on their in-house testing. To provide transparency and assurance, we commission independent third-party analysis through Janoshik to verify these specifications. Janoshik reports include an industry-standard margin of error of ±5%, which accounts for normal laboratory variability. For example, a reported result of 95% purity may still reflect up to 99% purity once the margin of error is considered. COA data is published exactly as received from Janoshik and is intended strictly for research use and reference only.
