Sharper focus without the jitters: Semax drives clarity and drive while Selank keeps anxiety dialed down, so you get clean, calm productivity from a single 20 mg blend. Contains 10 mg of each.

The Science Behind Brain Blend

Semax

A synthetic analog of a fragment of ACTH (the 4-10 sequence), stripped of the hormonal activity so what is left is the neuroactive part.

• Raises BDNF and NGF, the growth factors tied to neuron health, plasticity, and learning

• Modulates dopamine and serotonin signaling, which is where the focus and motivation effect comes from

• Slows the breakdown of enkephalins, contributing to its neuroprotective profile

The short version: it pushes the brain toward better signaling and supports the machinery behind memory and attention.

Selank

A synthetic analog of tuftsin, a peptide the body already makes as part of immune and brain signaling.

• Acts on the GABA system, the main calming pathway, which is the basis for its anxiety-reducing effect

• Influences serotonin balance and stabilizes mood without the sedation you get from typical anxiolytics

• Also nudges BDNF upward, so it overlaps with Semax on the neurotrophic side

The short version: it takes the edge off without dulling you, which is why it pairs so cleanly with a stimulating peptide.

Why they blend well

Semax brings the drive and mental sharpness, Selank keeps the stress response in check. Run together at 10 mg each, one balances the other so you get the cognitive lift without the wired, overclocked feeling.
