Description
A short peptide for a sharper mind — cognitive support with a Russian pedigree.
Semax is a synthetic heptapeptide derived from a fragment of ACTH (adrenocorticotropic hormone). Developed in Russia and used clinically there for decades, it supports cognitive function, memory, focus, mood, and neuroprotection. Semax works by increasing BDNF (brain-derived neurotrophic factor) and NGF (nerve growth factor) — the molecules your brain uses to build and maintain neural connections.
How It Works
- Increases BDNF & NGF — Boosts the neurotrophic factors essential for neuron growth and survival.
- Supports neurotransmitter balance — Modulates dopamine, serotonin, and acetylcholine signaling.
- Enhances memory formation — Improves hippocampal function and long-term memory encoding.
- Neuroprotective — Reduces oxidative stress and inflammation in brain tissue.
- Sharpens focus — Supports attention, executive function, and cognitive endurance.
- Rapid onset — Nasal delivery reaches the brain within minutes.
What It’s Used For
Cognitive enhancement: Focus, memory, mental clarity, learning capacity.
Neuroprotection: Stroke recovery, TBI recovery, cognitive aging support.
Mood & motivation: Depression adjunct, anhedonia, low drive.
