Our peptides are sourced from a supplier that conducts internal quality testing, and we also perform independent verification to ensure consistency and quality.
Certificates of Analysis (COAs) are not routinely provided. Updated or batch-specific third-party testing can be arranged at the customer’s request; however, all laboratory testing is performed externally and will incur an additional cost. COAs will only be provided once updated testing has been completed and paid for.
This approach ensures transparency while maintaining accurate, current, and responsibly conducted verification standards.
