Certificates of Analysis — Batch Documentation

Every compound sold by Optimal Genesis LLC is third-party tested for identity, purity, and stability by Janoshik Analytical Laboratory. Certificates of Analysis (CoA) are provided for each active batch below. Purity is verified at ≥99% before any product is listed for sale.

⚠ CoA documents represent quality testing conducted on our supplier’s compound by Janoshik Analytical. Batch-specific CoAs are updated as new testing is completed. Tirzepatide CoA is pending — available upon request at hello@optimalgenesis.co. All products meet a minimum purity standard of 99% as verified by independent third-party HPLC analysis.

What is a Certificate of Analysis?

A Certificate of Analysis (CoA) is a document issued by an accredited third-party laboratory confirming the identity, purity, and composition of a compound. All Optimal Genesis compounds are tested via High-Performance Liquid Chromatography (HPLC) — the gold standard for peptide purity verification.

CoAs are batch-specific. When new inventory arrives, a new CoA is generated and uploaded here within 48 hours. Each CoA includes the compound name, CAS number, batch number, test date, purity percentage, and the testing laboratory’s credentials.

For questions about a specific batch or to request a CoA directly, contact us at hello@optimalgenesis.co.
