COAs & Testing

Every compound in the Covalent Peptides catalog is supported by supplier-provided Certificate of Analysis (COA) documentation traceable to the production lot. Documentation is built into how we operate — not a feature we add on request.

What is on every COA

• Product name, lot number, and production date
• Independent third-party purity verification
• Identity confirmation
• Appearance and physical specifications

Independent third-party verification

Lot-level documentation is supplier-provided and reflects independent third-party analytical verification of identity and purity. Lots that do not meet specification are not released to our inventory.

How to request a COA

COA documentation is available for every lot we ship. There are three ways to access it:

• Before purchase — email compliance@covalentpeptides.com with the product and any specific documentation needs.
• With your order — every shipment is supported by COA documentation for the specific lot shipped, available by request when the order is processed.
• After purchase — you can request additional or duplicate COA documentation for any product or lot at any time at the email above.

Lot traceability

Every vial is labeled with its lot number. The lot number on your shipment matches the lot referenced on the COA documentation provided. If you maintain laboratory records, this lets you tie experimental data to a specific batch of compound — the way responsible research procurement should work.

Research-use-only notice

COAs document compound identity and purity for research-grade material. They are not pharmaceutical product specifications. All products are For Research Use Only — Not For Human Consumption.
