FAQ

A Certificate of Analysis is an official lab document that verifies your peptide quality. Key sections include purity, identity, appearance, and endotoxin levels. Each CoA is batch-specific and available on product pages when documentation is provided.

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 and is commonly used when preparing peptides for research handling.

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.

Lyophilized peptides can remain stable for 2+ years when stored properly. Once in solution, peptides generally remain stable for 4-6 weeks when refrigerated with bacteriostatic water, or 7-10 days with sterile water.

Orders are processed within 0-2 business days. Standard shipping usually takes 3-5 business days from fulfillment. Lyophilized peptides do not require cold shipping because they remain stable at room temperature during normal transit windows.
