Sharper memory & focus
Semax has been shown to improve attention, memory, and mental performance, and is prescribed for cognitive impairment.
Russian clinical use; human and animal cognition studies.
Wellness Peptides
Sharp focus without the jitters. Semax boosts memory, focus, and mental energy while Selank melts away stress and anxiety — together, calm and clear-headed.
Start Your EvaluationWhat it is
Semax is a peptide built from a fragment of ACTH, a natural brain hormone. It was developed in Russia, where it is a registered medicine used for stroke recovery, cognitive decline, and attention problems.
Selank is a peptide based on tuftsin, a natural immune peptide. It is also a registered medicine in Russia, prescribed for anxiety — without the sedation, memory fog, or dependence of common anti-anxiety drugs.

How it works
Semax rapidly increases BDNF — the brain's own 'fertilizer' for growing and protecting neurons — and boosts dopamine and serotonin activity tied to motivation and focus.
Selank modulates the GABA system — the same calming pathway targeted by anti-anxiety medications — and protects enkephalins, the body's natural mood-stabilizing peptides.
Potential benefits
Both peptides have been used clinically in Russia for years and studied in human trials. Here's what that research reports.

Semax is used in stroke care, where studies reported improved neurological recovery and increased BDNF levels in patients.
