Are Product COAs (Certificates of Analysis) included?

Yes — every lot we sell has its own Certificate of Analysis, and you can view and download the one that matches your exact lot.

We don't issue generic or representative paperwork. Each lot is released against its own lot-specific Certificate of Analysis (COA), so the results you're looking at correspond to the precise lot in your hands.

What's on the COA

Every COA reports the results of our 14-point analytical release program, including:

• Chromatographic purity and net peptide content (HPLC)
• Bacterial endotoxins (LAL)
• Sterility — confirmed by two independent laboratories: compendial USP <71> and rapid ScanRDI detection
• Heavy metals — arsenic, cadmium, chromium, lead, and mercury (ICP-MS)
• Residual solvents (GC-MS)
• Container-closure integrity and solubility
• Residual trifluoroacetic acid (TFA)

Analytical testing is performed under ISO/IEC 17025:2017 accreditation, and finished product is manufactured to cGMP-aligned quality systems.
