Semax & Selank vs Adamax
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.

Adamax is a modified version of Semax with an adamantane group attached, designed to enhance its nootropic effects and extend duration of action compared to standard Semax.
Full details →Side-by-Side Comparison
| Aspect | Semax & Selank | Adamax |
|---|---|---|
| Mechanism | 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. | Similar to Semax - enhances BDNF expression and modulates dopamine/serotonin systems. The adamantane modification may increase lipophilicity and CNS penetration. |
| Typical Dosage | 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. | Intranasal: 100-500mcg 1-2 times daily. Lower doses than standard Semax may be effective due to enhanced potency. |
| Administration | Primarily administered intranasally for rapid brain uptake. N-Acetyl versions (NA-Semax, NA-Selank) offer enhanced stability and potency. Can also be injected subcutaneously. | Intranasal spray is most common route. More stable than standard Semax. Often used for acute cognitive enhancement. |
| Side Effects | Semax may cause mild irritability or hair shedding. Selank may cause mild fatigue or nasal irritation. Both are generally well-tolerated. | Similar to Semax - possible irritability, hair shedding, or overstimulation. May have stronger effects than standard Semax. |
