How to Buy Semax

Semax is a synthetic heptapeptide derived from ACTH (adrenocorticotropic hormone) that is studied for its neuroprotective, nootropic, and immunomodulatory properties.

Like Selank, Semax was developed in Russia, where it is approved for clinical use. It remains under investigation in Western markets and is available here for research purposes only.

At Omrena, Semax is available in 5 mg lyophilised vials.

Semax acts through several neurobiological pathways:

→BDNF and NGF stimulation — Semax increases the production of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), two key proteins for neuronal survival, plasticity, and memory formation.

→Immune modulation — Semax has been shown to enhance the expression of pro-inflammatory cytokines in certain immune cell models, suggesting a role in immune system regulation.

→Cerebral blood flow — some studies suggest Semax improves microcirculation in the brain, contributing to its neuroprotective effects.

Every Semax batch is independently tested for purity (≥99% HPLC) and shipped lyophilised in sealed vials.
