Certificates of Analysis
Every Jartides batch is tested by an independent accredited laboratory before it ships, screened for identity, purity, potency and contaminants. Browse the current certificates below.
Independent third-party labHPLC-UV and LC-MSTested by Freedom Diagnostics
Six-point screening
Every batch, tested six ways
Purity on its own is not enough. Each production lot is screened across six analytical methods before it is cleared to ship.

- Understanding Our COAs
A Certificate of Analysis (COA) is a document issued by an independent third-party laboratory that confirms the identity, purity, and quality of a specific product batch. Each COA typically includes:
- HPLC Analysis – High-Performance Liquid Chromatography measures the purity percentage of the peptide.
- Mass Spectrometry (MS) – Confirms the molecular identity of the peptide by measuring its molecular weight.
- Batch Number – A unique identifier linking the COA to a specific production batch.
- Appearance & Solubility – Physical characteristics of the product as observed during testing.
We are committed to transparency and quality. If you have any questions about our testing or would like a COA for a specific product, please contact us.
