Selank 5mg + BAC Water – neuroregulatory peptide for stress, sleep and immunity.

• Modulation of the serotonergic and dopaminergic systems – restores emotional balance, reduces tension and anxiety.
• Increased BDNF expression – supports neuroplasticity and neuronal regeneration.
  GABA-influencing – naturally calms without sedation or numbness.
• Improved sleep quality and concentration – stabilizes circadian rhythm and facilitates mental recovery.
• Immunomodulatory effects – strengthens the immune response and reduces inflammation.

💡 Effect: peace, clarity of thought, better sleep and mental resistance to everyday stress.

SELANK and the nervous system and mood

SELANK modulates the activity of the dopamine and serotonin systems, stabilizing mood and reducing hyperactivity.

Clinical studies have shown it to reduce symptoms of anxiety and emotional tension while improving concentration and working memory.

SELANK and sleep and regeneration

The peptide regulates circadian rhythms by influencing the synthesis of serotonin and melatonin.

It facilitates falling asleep, deepens the deep sleep phase, and improves the body's regeneration. Thanks to its calming effect, it does not cause daytime drowsiness or addiction.

Figure 1. Effect of the Selank peptide on BDNF levels in the hippocampus of the tested subject, 3 and 24 h after administration of the peptide at doses of 250 and 500 μg/kg body weight. The following designations were used in the conducted study: 1 – control, 2 – Selank at a dose of 250 μg/kg, 3 – Selank at a dose of 500 μg/kg. Selank significantly increased the concentration of BDNF mRNA in the hippocampus by a factor of 1.5-2 compared to the control, 3 hours after administration at a dose of 250 or 500 μg / kg body weight. The result clearly shows a statistically significant 30% increase in the BDNF level in the rat hippocampus compared to the control value 24 h after the administration of the peptide at a dose of 250 or 500 μg/kg body weight, which proves its positive effect on maintaining and restoring normal cognitive functions of the body.

SELANK and oxidative stress and immunity

SELANK reduces levels of pro-inflammatory cytokines (including IL-6), which reduces oxidative stress and supports the immune system.

In vivo models have confirmed its anti-inflammatory and immunomodulatory effects, increasing resistance to infections and improving body homeostasis.

SELANK and cognitive functions

By influencing neurotransmitters and neurotrophic factors, SELANK supports memory, reaction speed, and mental clarity.

Studies have observed improved performance on cognitive tests and improved information processing under stress.
