Analytical transparency
COA Library
Every lot we release is sampled and sent to an independent laboratory. Purity is quantified by RP-HPLC against a reference standard and identity confirmed by mass spectrometry. The certificate below is matched to the lot code printed on your vial — check it before you open the seal.
1 · Find your lot code
The lot code is printed on the vial label directly beneath the peptide ID — for example AP-GHK-03 carries lot GHK-03.
2 · Match the certificate
Find the same lot code in the table below. If the code on your vial is not listed, contact us before use rather than assuming a match.
3 · Read the two numbers
HPLC purity as a percentage against the reference standard, and the observed mass from MS against the theoretical weight for the sequence.

What a certificate does not tell you
Read It Honestly
A Certificate of Analysis reports what an independent laboratory measured in a sample drawn from one lot. It confirms identity and purity for that material at that time. It is not a safety assessment, it makes no claim about suitability for any use in humans or animals, and it does not certify anything about how the material is handled after it leaves us.
If a lot ever fails to match its published certificate, contact us within 7 days with the lot code and we will replace it. See our Return Policy.
