Every lot is independently tested via High-Performance Liquid Chromatography (HPLC) and confirmed at ≥99% purity by Horizon Analytical, an accredited third-party lab. Mass spectrometry confirms molecular identity. Batch-specific Certificates of Analysis are available on our COA library and on request.

We accept all major credit and debit cards (Visa, Mastercard) and Apple Pay, processed securely through our payment gateway. Bank transfer and cryptocurrency are also available on request — email [email protected] for instructions.

Lyophilized (unreconstituted) vials are stable at room temperature for shipping and can be stored long-term in a freezer (-4°F / -20°C). Once reconstituted with bacteriostatic water, keep refrigerated at 36–46°F (2–8°C) and use within ~60 days.

Common research protocols reference 2mL of bacteriostatic water per 10mg of peptide, producing a 5 mg/mL concentration. Use our reconstitution calculator at /reconstitution/ for any specific dose calculations. Always consult published literature for your specific research protocol.
