COA Questions
What is a Certificate of Analysis (COA)?
A Certificate of Analysis is a document from an independent laboratory that verifies the purity, identity, and quality of a peptide. It includes test results from HPLC analysis, Mass Spectrometry, and other quality control measures.
Where can I find the COA for my product?
Every product page includes a link to view or download the current batch's Certificate of Analysis. You can also request specific COAs by emailing support@aminoclub.com with your order number.
How do I read a COA?
Key sections include: Purity % (should be 99%+), Molecular Weight (confirms identity), Appearance (lyophilized powder), and Sequence (amino acid sequence). Our COAs include clear explanations of each test result.
Are your labs accredited?
Yes, we partner with ISO 17025 accredited laboratories that specialize in peptide analysis. These independent facilities have no financial interest in our products, ensuring unbiased results.
How often are peptides tested?
Every production batch undergoes full testing before release. We maintain rigorous quality control with no exceptions—if a batch doesn't meet our 99%+ purity standard, it's not sold.
