Research peptides you can trust

Every batch is verified at 99%+ identity purity using HPLC and Mass Spectrometry by accredited U.S. laboratories. The full Certificate of Analysis is included with every order.

A Certificate of Analysis is an official lab document that verifies your peptide’s quality. Key sections include: Peptide Purity (should be 99%+), Net Peptide Content (measured mg vs the label), Identity (confirmed against a certified reference standard), Appearance, Fentanyl Screen, Heavy Metals, Sterility, and a quantitative Endotoxin result. Each CoA is batch-specific: find it on the product page or scan the QR code on your vial.

Mola H2O is sterile, pyrogen-free water intended for research reconstitution workflows. It is sold for laboratory use only.

Store lyophilized products at -20°C away from light. Reconstituted products should be kept at 2-8°C and used within the stability window stated in the documentation.

Lyophilized products remain stable for 24+ months at -20°C. Reconstituted products are typically stable for around 30 days at 2-8°C.
