Frequently Asked Questions
What purity level are your peptides and how is it verified?
All Optitide peptides are guaranteed 99%+ pure. Each batch is independently tested by accredited U.S. laboratories using HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry. We provide a Certificate of Analysis (CoA) with every order showing exact purity percentages, molecular weight verification, and optitide acid sequence confirmation.
What is a Certificate of Analysis (CoA) and how do I read it?
A Certificate of Analysis is an official lab document that verifies your peptide’s quality. Key sections include: Purity (should be 99%+), Identity (confirms correct peptide via mass spec), Appearance (should match product description), and Endotoxin levels (should be below 1 EU/mg). Each CoA is batch-specific and available on product pages.
What is bacteriostatic water?
Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. It is a standard laboratory supply used in research settings. We offer pharmaceutical-grade BAC water in our accessories section.
How should I store peptides?
Lyophilized (freeze-dried) peptides are very stable. For short-term storage (under 3 months), room temperature in a cool, dark place is fine. For long-term storage, refrigerate at 2-8°C or freeze at -20°C. Avoid repeated freeze-thaw cycles. Properly stored lyophilized peptides can remain stable for 2+ years.
