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.

“Got the IGF-1 LR3 in for a muscle-cell growth study and everything checked out. Reconstituted crystal clear, no cloudiness or floaties. Shipping to JB was fast and the packaging was plain and secure. Will definitely reorder.”
“First order of IGF-1 LR3 from Doctides and I'm impressed. Exactly the response profile I was after for IGF signalling. Delivery took an extra day to KL, but the quality made up for it. Will definitely reorder.”
“Been running IGF-1 LR3 in a muscle-cell growth study for a few weeks now. Purity has been consistent lot to lot, which matters most for IGF signalling. The data around IGF signalling has been encouraging so far. Confident buying here again.”
“This is my second lot of IGF-1 LR3 for a muscle-cell growth study. Powder was well-lyophilised and dissolved in seconds. Exactly the response profile I was after for IGF signalling. Confident buying here again.”
“Third time buying IGF-1 LR3 — consistency is why I stay. Purity has been consistent lot to lot, which matters most for IGF signalling. The data around IGF signalling has been encouraging so far. Support answered my questions quickly too.”
