Side-by-Side Comparison

AspectAdamaxSemax & Selank
MechanismSimilar to Semax - enhances BDNF expression and modulates dopamine/serotonin systems. The adamantane modification may increase lipophilicity and CNS penetration.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 DosageIntranasal: 100-500mcg 1-2 times daily. Lower doses than standard Semax may be effective due to enhanced potency.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.
AdministrationIntranasal spray is most common route. More stable than standard Semax. Often used for acute cognitive enhancement.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 EffectsSimilar to Semax - possible irritability, hair shedding, or overstimulation. May have stronger effects than standard Semax.Semax may cause mild irritability or hair shedding. Selank may cause mild fatigue or nasal irritation. Both are generally well-tolerated.
