Research background

About Semax

Semax is a seven-residue peptide: the ACTH(4–7) sequence Met-Glu-His-Phe followed by Pro-Gly-Pro, an extension that slows its breakdown by peptidases. It was developed at the Institute of Molecular Genetics in Moscow, which also produced Selank.

Research on Semax concentrates on neurotrophins and gene expression in the brain: it binds in the rat basal forebrain and raises BDNF protein there (Dolotov et al., 2006), activates transcription of neurotrophin genes (Dmitrieva et al., 2010) and acts on dopaminergic and serotonergic systems (Eremin et al., 2005). It is listed in Cognition & sleep.

Semax FAQ

What is the difference between Semax and N-acetyl Semax?

N-acetyl Semax carries an acetyl group on the N-terminal methionine, so it is a different compound with a different mass. This page is Semax itself (813.9 g/mol), and the COA of your lot confirms the form you receive.

Why are there so many Semax specifications?

Six are listed — 2 mg, 5 mg, 10 mg, 11 mg, 15 mg and 30 mg — so the kit can match the scale of your work. Each is sold by the kit of 10 vials.

How to order

Kit and minimum
Semax is sold by the kit: 10 vials of one specification (2 mg, 5 mg, 10 mg, 11 mg, 15 mg and 30 mg). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.
Price
Reference prices are listed per kit above, from $88.55. The kits of your whole quote list count together — 5–19 kits are 20% off every kit, and from 20 kits our sales team quotes the price — so Semax adds up with anything else you order; your written quote has the final price.
Documents
Every lot has its own COA with HPLC purity and MS identity; the order ships with the certificate of its lot, and our sales team sends it before you order if you ask.
Shipping
Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment
Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal
Listed under Cognition & sleep — Neuropeptides such as Semax, Selank, DSIP and Pinealon.
