Frequently Asked Questions

All NexaPep products are sold strictly for in-vitro laboratory and scientific research. They are not intended for human or animal consumption, diagnostics, or therapeutic use of any kind.

Yes. Every batch undergoes independent third-party analysis for identity, purity, and concentration. A Certificate of Analysis (COA) is made available for each product lot.

Our research peptides are synthesized to a minimum of 99% purity as verified by HPLC and mass spectrometry. Exact values are published on each product's COA.

Lyophilized peptides are shipped in temperature-protected packaging. For long-term stability we recommend storing unreconstituted vials at -20°C, away from light.
