Product Description Semax 

This research blend combines Semax and Selank, two synthetic heptapeptides developed for laboratory investigations of neuroprotective mechanisms. Semax is an ACTH(4-10) analog that modulates BDNF expression and neurotransmitter systems, while Selank is a tuftsin derivative that affects GABAergic signaling and immune modulation pathways.
Both compounds are used in studies examining neurochemical signaling, stress response mechanisms, and learning and memory processes in controlled laboratory settings. Supplied as pharmaceutical-grade lyophilized powder with third-party verified purity testing for qualified research institutions conducting in vitro research applications only.

Semax  benefits

Semax boosts brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), promoting neuroplasticity, memory formation, and learning in healthy users and those with cognitive deficits.
It elevates dopamine and serotonin for improved mood, reduced anxiety, stress resilience, and motivation, often aiding high-performers.
Neuroprotective effects shield against oxidative stress, ischemia, inflammation, and hypoxia, supporting stroke recovery, optic nerve health, and endurance.
