— About this compound
Semax is a synthetic heptapeptide composed of an N-terminal ACTH(4-7) tetrapeptide (Met-Glu-His-Phe) extended with the C-terminal tripeptide Pro-Gly-Pro. The Pro-Gly-Pro extension dramatically increases plasma stability compared to the parent ACTH fragment.
Semax is one of the most-studied compounds in the Russian neuropeptide literature, with a substantial body of preclinical work on neurotrophic factor expression, monoamine neurotransmission, and behavioral models.

— 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.
