Peptides are short chains of amino acids — the same building blocks that make up proteins. In research, specific sequences are studied for their signalling roles across metabolism, tissue repair, and cellular health. All products on this site are intended strictly for laboratory and research use.
Lyophilised (freeze-dried) peptides are reconstituted with bacteriostatic water before use. The required volume depends on your target concentration — use our peptide calculator to determine the exact amount. Store reconstituted vials refrigerated and use within the validated window.
Unopened lyophilised vials are stable at room temperature for short periods but are best kept refrigerated (2–8°C) and away from light. Once reconstituted, refrigerate at all times. For long-term storage, freeze the lyophilised powder at -20°C.
In-stock orders placed before 1pm ET dispatch same day in plain, insulated, discreet packaging. Most addresses receive delivery within 1–3 business days via express courier, with tracking provided at dispatch.
