Research-grade peptides.
5X tested. Shipped fast.

Every batch undergoes our 5-point testing protocol: endotoxin testing, sterility verification, heavy metal screening, quantity, and high-purity HPLC analysis with mass spectrometry confirmation. Full Certificates of Analysis from third-party laboratories are published on our test results page — every batch, every time.

Our compounds ships as lyophilized (freeze-dried) powder, which is highly stable. For short-term storage (under 3 months), a cool, dark location at room temperature is sufficient. For long-term storage, refrigerate at 2–8°C or freeze at −20°C. Avoid repeated freeze-thaw cycles. Properly stored lyophilized compounds remains stable for 2+ years. Once reconstituted, use within 4–6 weeks when refrigerated with bacteriostatic water.

All orders are processed and shipped within 24 hours on business days. Standard domestic delivery takes 2–5 business days with full tracking. We also offer Express shipping for faster delivery. Orders over $400 ship free. All packages are shipped in discreet, unmarked packaging.
