Quality & Testing
Every SEQN product is manufactured and verified against its reference sequence, then undergoes third-party testing to confirm identity, purity, and quality before it ships.
Certificates of Analysis (COAs) are available upon request for any product in our catalog. To request one, include the product name and lot number (if available) in your message and we'll send the corresponding COA directly to you.
Each Certificate of Analysis documents the results of independent third-party testing, including identity confirmation, purity percentage, and quality/contaminant screening for the corresponding product and lot.
For questions about testing methodology or a specific batch, reach out via our contact page.
