Why the intranasal format

Semax is one of the peptides where the route of administration is central to the research rather than incidental. Intranasal delivery gives direct nose-to-brain transport along the olfactory and trigeminal nerve pathways, which partially bypasses the blood-brain barrier and avoids the first-pass metabolism that breaks down small peptides taken orally. Research indicates this achieves meaningfully higher central nervous system exposure than other routes.

This is why Semax was developed as an intranasal formulation, and why the majority of the published clinical literature on it uses the intranasal route.

Research Focus

Semax is a synthetic analogue of the ACTH(4-10) fragment, developed in Russia and studied extensively there since the 1980s. Research indicates it influences expression of BDNF and NGF — two neurotrophic factors involved in neuronal growth and survival. Published studies have examined its effects on cognition, attention and memory, its neuroprotective activity in models of cerebral ischaemia, and its use in stroke recovery, where it has been applied clinically in Russia.

Research on Semax includes both human clinical studies, largely published in Russian-language journals, and animal models. Our summary of the published literature is here: Semax Dosage: What Studies Have Actually Investigated.

Testing & Certificates of Analysis

Sprays are prepared from the same independently tested material as our powder vials — HPLC purity and mass-spectrometry identity, certified per batch and published on our lab results page.
