Overview

Two Peptides. One Goal: Cognitive Mastery.

Semax and Selank are synthetic neuropeptides developed by leading neuroscientists that have been clinically studied for their ability to enhance cognition, protect the brain, and balance neurotransmitter systems — without the side effects of conventional stimulants or benzodiazepines.

At Prime Vitality Wellness, Dr. Shiv Kumar Goel integrates these precision neuropeptides into personalized functional medicine protocols. Whether you're struggling with brain fog, performance anxiety, burnout, or want to operate at your highest cognitive potential — Semax and Selank offer a scientifically grounded approach to mental optimization rooted in both Eastern and Western medicine principles.

Unlike stimulants that deplete neurotransmitter stores, these peptides work by modulating the brain's own signaling pathways — supporting long-term neurological health while delivering immediate functional benefits. They represent the frontier of precision neurological wellness.

The Peptides

Discover Semax & Selank for Peak Cognitive Performance

Complementary in action, each peptide targets a distinct aspect of cognitive performance — making them a powerful combination for comprehensive brain optimization.

Semax

ACTH(4-10) Derivative · Nootropic · Neuroprotective

A synthetic analog of adrenocorticotropic hormone (ACTH 4-10), engineered to enhance dopaminergic tone and massively upregulate BDNF and NGF. Originally developed for stroke rehabilitation in Russia, Semax is now recognized as one of the most potent research-grade cognitive enhancers and neuroprotective peptides available.

  • Enhances memory consolidation, recall speed, and verbal fluency
  • Increases BDNF and NGF — supports neuron growth and repair
  • Optimizes dopamine tone for motivation and focus without depletion
  • Neuroprotective against hypoxia, ischemia, and oxidative stress
  • Improves cognitive performance under fatigue and psychological stress
  • Clinically studied for stroke recovery and vascular cognitive impairment
  • Research shows promise for Alzheimer's disease prevention strategies

Selank

Tuftsin Analog · Anxiolytic · Mood Stabilizer

A synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from tuftsin, developed by the Russian Academy of Sciences. Selank functions as both a neuropeptide and a non-sedating anxiolytic, modulating GABA, serotonin, and dopamine pathways to deliver calm, clear-headed focus — without the dependency or withdrawal effects of benzodiazepines.

  • Reduces anxiety and stress without sedation or cognitive blunting
  • Upregulates BDNF for improved focus, memory, and neuroplasticity
  • Modulates GABA — calms overactive neural circuits driving anxiety
  • Normalizes serotonin and dopamine for balanced mood and motivation
  • Inhibits enkephalin degradation — naturally boosts mood resilience
  • Anti-inflammatory: suppresses IL-6 and TNF-α neuro-inflammatory markers
  • No known addiction potential or withdrawal effects in clinical studies
Mechanisms of Action

How These Cognitive Peptides Work

Semax and Selank act on overlapping yet complementary neural pathways, modulating the brain's own molecular machinery to enhance performance, protect neurons, and restore neurochemical balance.

BDNF Upregulation

Both peptides significantly increase brain-derived neurotrophic factor — the brain's key growth protein supporting synapse formation, long-term potentiation (LTP), and survival of hippocampal neurons critical for memory and learning.

Dopaminergic Modulation

Semax optimizes dopamine system efficiency — enhancing motivation, focus, and reward circuits without depleting dopamine stores. This differentiates it from stimulants, providing a sustainable cognitive lift rather than a crash-and-burn cycle.

GABAergic Regulation

Selank enhances GABA transmission — the brain's primary inhibitory system. By calming overactive neural circuits that perpetuate anxiety, it creates space for cognitive clarity and focused attention without benzodiazepine-like sedation.

Neuroprotection

Semax has demonstrated neuroprotective effects in clinical trials involving ischemic stroke, optic nerve damage, and cognitive disorders of vascular origin — protecting neurons from hypoxic damage and oxidative stress.

Neuroimmune Balance

Selank's tuftsin heritage provides immunomodulatory properties: it suppresses neuroinflammatory cytokines (IL-6, TNF-α) while supporting immune resilience, creating an internal environment conducive to optimal brain function.

NGF & Cholinergic Support

Semax uniquely upregulates nerve growth factor (NGF) in the hippocampus and basal forebrain — supporting cholinergic neurons critical for memory and making it especially relevant to age-related cognitive decline and Alzheimer's research.

Clinical Research

Evidence-Based Brain Optimization

In a landmark clinical study, a single intranasal dose of Semax (1mg) in fatigued male volunteers resulted in 71% accuracy on memory tests vs. 41% in controls, with benefits sustained for up to 24 hours. Semax also improved functional outcomes in stroke patients by increasing plasma BDNF — leading to enhanced Barthel index scores.

In Alzheimer's disease models, both Semax and its derivatives significantly reduced amyloid plaques in the cortex and hippocampus — demonstrating high potential for therapeutic and preventive strategies. resting-state fMRI studies show Semax increases volume in the medial frontal cortex, associated with better information processing and episodic memory.

Selank has shown anxiolytic efficacy comparable to benzodiazepines in multiple Russian clinical trials — without sedation, dependency, or cognitive impairment. Its neuroimmune modulation is particularly valuable for individuals with stress-driven neuroinflammation.
