Frequently Asked Questions

Peptides are short chains of amino acids linked by peptide bonds. They are naturally occurring in the body and act as signaling molecules involved in a wide range of biological processes — from hormone regulation to cellular repair. In research settings, synthetic peptides are studied for their interactions with specific receptors, enzymes, and pathways.

Our catalog includes GLP-1 receptor agonists (Semaglutide, Tirzepatide, Retatrutide), tissue repair peptides (BPC-157, TB-500), copper peptides (GHK-Cu), growth hormone-releasing analogs (Sermorelin, Tesamorelin, CJC-1295), nootropic peptides (Selank, Semax), melanocortin peptides (MT-2), and research blends. We also carry bacteriostatic water for reconstitution.

Lyophilized (freeze-dried) peptides should be stored at –20°C or below for long-term stability, away from light and moisture. Once reconstituted, store at 2–8°C and use within the timeframe recommended for each compound. Always handle under sterile conditions appropriate to your research protocol.

No. Our products are research chemicals sold under a Research Use Only (RUO) designation. They have not been evaluated or approved by the FDA for any therapeutic, diagnostic, or clinical use. They are provided solely for in vitro and laboratory research applications by qualified researchers.

Orders are processed within 2–3 business days of receipt, excluding weekends and public holidays. Delivery estimates begin once the order has been dispatched and vary based on your location, carrier availability, and other factors. A tracking number is provided upon fulfillment. See our Shipping Policy for full details.
