Researcher sign-in required

All Amino Club 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 amino acid sequence confirmation.

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.

Amino H2O is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. It is a standard laboratory supply used in research settings. We offer Amino H2O in our accessories section as research supply.

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.

Lyophilized (freeze-dried) peptides are highly stable and can last 2+ years when stored properly at -20°C or 2-8°C. Always store away from light and avoid repeated temperature fluctuations.

Orders are processed within 0-2 business days. Standard shipping takes 3-5 business days from fulfillment. Every order includes free shipment protection. Lyophilized peptides don't require cold shipping—they're stable at room temperature. All orders ship in discreet, unlabeled packaging.
