Selank + Semax 20 mg is a 1:1 research blend containing 10 mg Selank and 10 mg Semax. Selank research is associated particularly with stress, anxiety and GABAergic signalling, while Semax research focuses more strongly on neurotrophic signalling, learning, memory and experimental neuroprotection.

Research Overview
About Selank + Semax 20 mg Blend
Selank is the heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP), based on the tuftsin sequence with a Pro-Gly-Pro extension. Semax is Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP), based on ACTH(4-7) with the same C-terminal Pro-Gly-Pro motif. Although both peptides have individual research histories, the pre-mixed 1:1 injectable blend does not have an established controlled human clinical dosing regimen. Individual-peptide findings should therefore not be presented as proof of efficacy or synergy for the combination.
How It Works in Research
Selank and Semax are different peptides with different parent sequences. Selank research has reported effects on genes involved in GABAergic neurotransmission and other neuronal signalling pathways. GABA is the brain's principal inhibitory neurotransmitter system and is important in neuronal excitability and stress-related signalling. Semax research has focused strongly on neurotrophic pathways. Animal studies have reported effects on brain-derived neurotrophic factor (BDNF) and BDNF/TrkB signalling. BDNF participates in neuronal survival, synaptic plasticity, learning and adaptation. The rationale for the blend is therefore complementary pathway research: Selank-associated GABA/stress signalling alongside Semax-associated neurotrophic and cognitive signalling. Controlled trials establishing synergy, superiority or an optimal ratio for the injectable combination have not been established.
Research Applications
Stress and anxiety-related signalling • GABAergic neurotransmission • BDNF and TrkB signalling • Learning and memory • Attention and cognition • Synaptic plasticity • Experimental neuroprotection • Neurotransmitter gene expression
In simple terms, Selank is researched more for calming, stress-response and GABA-related signalling, while Semax is researched more for brain-growth-factor signalling, learning and memory. Combining them creates a research preparation for studying both pathways together.

Key Research Characteristics
20 mg total: 10 mg Selank + 10 mg Semax • Two distinct synthetic heptapeptides • Shared C-terminal Pro-Gly-Pro motif • Selank: TKPRPGP • Semax: MEHFPGP • GABAergic and neurotrophic research focus • Combination-specific human clinical evidence is not established
Potential Benefits in Research
Parent Selank has been investigated for anxiety, stress-related effects and GABAergic signalling.
Parent Semax has been investigated for learning, memory and neurotrophic signalling.
Semax animal research has demonstrated effects on BDNF-related pathways.
The 1:1 blend allows both peptides to be studied in a single preparation.
Safety Profile
Possible local irritation with injectable research preparations.
Neurological or subjective effects may vary with exposure.
Combination effects and interactions have not been adequately characterized in controlled clinical trials.
Identity and purity should be verified for both peptide components.
Research Applications
