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.

“Ordered Semax for a cognition study and it performed exactly as described. Powder was well-lyophilised and dissolved in seconds. No stability issues across the study window. Easily my go-to supplier now.”
“Reordered Semax again for a cognition study. Purity has been consistent lot to lot, which matters most for focus and neuroprotection research. Label could be a touch clearer, but the COA sorted it out. Confident buying here again.”
“This is my second lot of Semax for a cognition study. Batch-to-batch consistency has been reliable. Exactly the response profile I was after for focus and neuroprotection research. Will definitely reorder.”
“Third time buying Semax — consistency is why I stay. Lab report was published for the exact lot, great for record-keeping. Clean handling and good tolerability in the model. Support answered my questions quickly too.”
“Ordered Semax for a cognition study and it performed exactly as described. The COA matched the label, tested well above 99% purity. Arrived in Ipoh within two days, discreet and cold-packed. No complaints — exactly what a research budget needs.”
“Reordered Semax again for a cognition study. The third-party Janoshik numbers lined up with the site. No stability issues across the study window. Highly recommend for serious research work.”
“Third time buying Semax — consistency is why I stay. Results in the model line up with what the literature suggests for focus and neuroprotection research. Delivery took an extra day to Ipoh, but the quality made up for it. Highly recommend for serious research work.”
