Semax

Semax is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10) with a C-terminal Pro-Gly-Pro extension that enhances stability. Within Russian neuroscience research, Semax has been studied for decades due to its influence on cognition, BDNF signaling, and neuroprotection.

Semax lyophilisate is produced according to high quality standards and verified with HPLC to a purity of ≥ 99%.

Research relevance

• BDNF expression — models regarding Brain-Derived Neurotrophic Factor and synaptic plasticity.
• Cognition and memory — preclinical studies on learning ability and attention focus.
• Neuroprotection — models regarding ischemic damage and oxidative neuronal stress.
• Comparative studies with Selank — often studied side-by-side for various neuropeptide effects.

Frequently Asked Questions

What is Semax?

Semax is a synthetic heptapeptide derived from ACTH(4-10) with a Pro-Gly-Pro tail. The modification makes it resistant to enzymatic degradation while retaining neurotropic activity.

How does Semax differ from Selank?

Both are Russian neuropeptides, but Semax is derived from ACTH and targets cognition and BDNF signaling. Selank is derived from Tuftsin and targets anxiolysis and GABA modulation.

What purity is guaranteed?

Janoshik validates every batch for HPLC purity ≥ 99%, with additional analysis of heavy metals and endotoxins.

How should Semax be stored?

Store the lyophilisate refrigerated (2–8 °C), protected from light and moisture. Do not open vials until just before reconstitution.
