— About this compound
Selank is a synthetic heptapeptide consisting of the human tuftsin tetrapeptide (Thr-Lys-Pro-Arg) extended with the C-terminal tripeptide -Pro-Gly-Pro. The C-terminal extension confers significant proteolytic resistance, supporting longer in-vivo activity than the parent tuftsin.
Selank is one of two Russian-developed heptapeptides commonly co-studied in the neuropeptide literature; the other (Semax) is structurally distinct but is often cited alongside Selank in research on neurotrophic and behavioral endpoints.
— Mechanism
Reported effects on GABAergic and serotonergic neurotransmission in preclinical research. Modulates BDNF and NGF expression in some rodent models. Acts intranasally or peripherally with reported CNS bioavailability.
— How it’s made
Every Nexa batch follows the same documented path. Five steps, every one verifiable.
01
Sourcing
Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.
02
Compounding
Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.
03
Verification
Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every batch before it leaves the lab. The chromatogram is archived.
04
Release
No batch ships until an independent laboratory has returned its identity and purity results and the certificate is published in the COA library.
05
Dispatch
Sealed vials with a QR code on the label that opens the COA library. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.
