What is Semax?

Semax (ACTH(4-10) derivative — cognitive neuropeptide) is a 7-amino acid synthetic ACTH(4-10) derivative. ACTH(4-10) derivative upregulating BDNF and NGF expression in multiple brain regions, modulating monoaminergic systems (dopamine, serotonin, noradrenaline), and producing neuroprotection in cerebral ischemia models. Approved as nasal spray in Russia. Greater potency and duration than parent ACTH(4-10).

Frequently Asked Questions

How do I reconstitute Semax?
Add 1–2mL bacteriostatic water to the lyophilized Semax vial. Semax is a heptapeptide (ACTH(4-10)-Pro-Gly-Pro) that dissolves readily. Swirl gently to a clear colourless solution. Some researchers dilute further with saline for intranasal administration.
How should Semax be stored?
Store lyophilized at −20°C. Reconstituted: 2–8°C for up to 28 days. Semax is relatively stable — the Pro-Gly-Pro C-terminal extension was specifically added to increase proteolytic resistance vs. native ACTH(4-10).
What purity is QSC Semax and how is it verified?
QSC Semax (ACTH(4-10)-Pro-Gly-Pro) is ≥99% HPLC pure with MS-confirmed 7-amino acid sequence on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
