Peptide Certificate of Analysis (COA) Library
Every research peptide we sell ships with a Certificate of Analysis. Our COA library catalogs lot-level documentation across the Amino Fuel Labs product range and is open to qualified researchers who want to verify quality before ordering.
What a COA confirms
A research peptide COA documents identity, appearance, manufacture and retest dates, and HPLC purity. Our COAs are produced by an independent third-party laboratory and tied to the lot number printed on the vial label, so investigators can match the document to the physical sample.
How to access lot documentation
The COA library is available on our lab reports page. If you need the COA for a specific lot you have already received, contact us with the lot number and we will respond with the document on file. We do not modify COAs after they are issued by the testing lab.
Why COA-supported quality matters
In any research workflow that compares conditions across vials, knowing that each lot has documented purity reduces a major source of variance. Our COA program is designed to make that verification fast and unambiguous — and to remind every customer that products are research use only, not for human consumption.
