Semax & Selank
A nootropic combination pairing two Russian-developed peptides for cognitive enhancement. Semax provides stimulating focus and neuroprotection while Selank offers anxiolytic and mood-stabilizing effects, creating a balanced cognitive enhancement stack.
Mechanism of Action
Semax enhances BDNF expression and modulates dopamine and serotonin systems for improved focus, memory, and neuroprotection. Selank affects BDNF and GABA systems, providing anxiolytic effects and immune modulation. Together they support cognitive function while managing stress and anxiety.
Typical Dosage (Research)
Semax: 200-600mcg intranasally 2-3 times daily. Selank: 250-500mcg intranasally 2-3 times daily. Can be used together or alternated based on needs.
Primarily administered intranasally for rapid brain uptake. N-Acetyl versions (NA-Semax, NA-Selank) offer enhanced stability and potency. Can also be injected subcutaneously.
Side Effects & Risks
Semax may cause mild irritability or hair shedding. Selank may cause mild fatigue or nasal irritation. Both are generally well-tolerated.
Limited clinical data outside of Russia. Semax may affect thyroid function with prolonged use. Long-term effects not well documented in Western studies.
Who Uses Semax & Selank
Students and professionals seeking cognitive enhancement, those managing stress and anxiety while needing mental clarity, individuals interested in neuroprotection and brain health.
