Research background

About Selank

Selank is a seven-residue peptide built on tuftsin, a natural immunomodulatory tetrapeptide (Thr-Lys-Pro-Arg), extended by Pro-Gly-Pro to slow its breakdown. It was developed at the Institute of Molecular Genetics in Moscow, alongside Semax.

Research on Selank looks at anxiety-related behaviour and at possible mechanisms, such as inhibition of enkephalin-degrading enzymes (Zozulya et al., 2001) and changes in genes of GABAergic neurotransmission (Volkova et al., 2016); other papers follow inflammation-related genes in mouse spleen (Kolomin et al., 2011). It is listed in Cognition & sleep.

Selank FAQ

How is Selank related to Semax?

Both come from the same Moscow institute and both carry a Pro-Gly-Pro extension, but they start from different natural peptides: Selank from tuftsin, Semax from a fragment of ACTH. They are separate products with different sequences and masses.

Which Selank specifications are listed?

5 mg, 10 mg and 11 mg, each sold by the kit of 10 vials. The COA of your lot reports HPLC purity and MS identity against 751.9 g/mol.

How to order

Ordering Selank from Medabol

Kit and minimum: Selank is sold by the kit: 10 vials of one specification (5 mg, 10 mg and 11 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 Selank 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.
