All peptides are packed tightly in multiple layers of protection to ensure product safety during transit. Because our peptides ship in lyophilized (freeze-dried) form, insulated packaging is unnecessary to maintain stability. The multiple protective layers also help insulate each vial from temperature fluctuations during shipping, keeping your product secure from start to finish.

All of our peptides are manufactured to 99%+ purity standards. Each batch undergoes rigorous third-party testing by HPLC and mass spectrometry, and a Certificate of Analysis (COA) is available for every product on its product page.

Lyophilized (powder) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerator) for short-term. Once reconstituted, store at 2-8°C and use within 4-6 weeks. Always protect from light and avoid repeated freeze-thaw cycles.

Lyophilized peptides have a shelf life of 2+ years when stored properly at -20°C. Reconstituted peptides should be used within 4-6 weeks when refrigerated. Each product includes a lot-specific expiration date.

Use our Research Water for reconstitution.

Research Water is sterile water containing 0.9% benzyl alcohol as a preservative. It prevents bacterial growth and allows reconstituted peptides to remain stable for 4-6 weeks when refrigerated.

Yes, every batch is tested by independent, accredited laboratories using HPLC for purity verification and Mass Spectrometry for identity confirmation. Test results are published on each product page as Certificates of Analysis (CoA).

Our peptides are synthesized in USA-based, FDA-registered facilities following strict cGMP guidelines. We maintain complete supply chain transparency and never source from overseas manufacturers.
