Purity
Target purity ≥99% by HPLC. The binding value for any vial is the result on that lot’s Certificate of Analysis.
Batch documentation
Contact support with your order or batch number to request the analytical record for a specific lot, or use COA Verification.
support@primelabs.bioWhat a COA demonstrates
Batch-specific identity verification, purity by validated analytical methods (e.g. HPLC), and third-party laboratory testing records for the referenced lot.
What a COA does not demonstrate
Clinical efficacy, safety for human or veterinary use, or suitability for any application outside qualified laboratory research.
Quality Assurance
Each lot is supported by batch-specific analytical documentation used to verify identity and purity. The Certificate of Analysis is the binding record for that vial.
