Third-Party Tested Peptides with COAs
Every PX1 peptide lot is independently tested by an ISO 17025-accredited laboratory. HPLC purity and mass-spec identity data are documented on a certificate of analysis (COA) available on request.
Quick answer
Every PX1 peptide lot is independently tested by an ISO 17025-accredited laboratory. HPLC purity and mass-spec identity data are documented on a certificate of analysis (COA) available on request.
Key takeaways
- Each lot is analyzed for peptide identity (mass spec), purity (HPLC, typically ≥99%), net peptide content and, where relevant, endotoxin.
- Testing is performed by third-party ISO 17025-accredited laboratories, not just in-house — the standard clinics and research labs expect before qualifying a supplier.
What We Test
Each lot is analyzed for peptide identity (mass spec), purity (HPLC, typically ≥99%), net peptide content and, where relevant, endotoxin. Results are documented on the COA.
Accredited, Independent Labs
Testing is performed by third-party ISO 17025-accredited laboratories, not just in-house — the standard clinics and research labs expect before qualifying a supplier.
