Research background

Semax is a heptapeptide derived from ACTH: it reproduces the 4-7 fragment of that hormone and adds a three amino acid tail (Pro-Gly-Pro) that protects it from peptidases. The fragment lacks the hormonal activity of full ACTH, which makes it possible to study its effects on the nervous system in isolation.

Research has centered on the expression of neurotrophic factors — BDNF and NGF above all — on neuroprotection in ischemia models, and on cognition. It matters where that literature comes from: the molecule was developed in Russia and most studies are published there, with little independent replication elsewhere.

Reconstitution and handling

Work on a clean surface and disinfect the vial stopper with an alcohol wipe before piercing it.
Add the bacteriostatic water slowly, letting it run down the inner wall of the vial rather than landing on the powder.
Do not shake. Swirl the vial gently until the lyophilized powder has fully dissolved: vigorous agitation degrades the peptide.
The solution should come out clear. If it turns cloudy or shows suspended particles, do not use it.
