Semax is a synthetic heptapeptide derived from ACTH(4-10) with a Pro-Gly-Pro tail that blocks rapid enzymatic degradation. It is studied for BDNF expression and dopaminergic modulation, most often in intranasal preparations.
Reference data researchers look up before ordering semax. Every lot ships with documentation matching the batch number printed on the vial.
Each semax lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.
Semax ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.
PX1 Research synthesizes and fills semax in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

Semax derives from ACTH and is studied for BDNF and focus endpoints; selank derives from tuftsin and is studied for anxiolytic and GABAergic endpoints.
Intranasal delivery uses olfactory transport toward the CNS and avoids the near-instant proteolysis semax undergoes in circulation.
Yes. Every semax lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.
Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
