Comprehensive data for clinical research and laboratory management.
What purity level are your peptides and how is it verified?
All Certa Research compounds are guaranteed at ≥99% purity. Each batch undergoes independent HPLC and Mass Spectrometry testing at accredited U.S. laboratories to ensure molecular identity and purity.
Reconstitution & BAC Water
Peptides should be reconstituted with Bacteriostatic Water (0.9% Benzyl Alcohol). This prevents bacterial growth and extends the stability of the solution for up to 30 days when refrigerated.
Shipping & Storage
Lyophilized peptides are stable at room temperature during transit. Upon arrival, store at 2°C to 8°C. For long-term storage exceeding 6 months, maintain at -20°C.
What is a CoA and how to read it?
The Certificate of Analysis (CoA) is your proof of quality. It confirms molecular mass, HPLC purity percentage, and compound identity. We provide full transparency with every batch.
