Nootropic Brain Spray

Powerful trio of Selank, Semax, and Oxytocin to optimize brain function and mood.

Selank increases cognitive abilities by increasing production of BDNF (Brain-Derived Neurotrophic Factor).

Selank is a peptide analog of the human tetrapeptide Tuftsin and mimics many of Tuftsin's anxiolytic and immune modulating benefits.   Selank's primary application is for its anti-anxiety and anti-depressant effects on stress resilience and mood.   One molecular mechanism by which Selank operates is by allosterically modulating the GABAergic system.  Selank also acts through the dopamine and serotonergic systems, which is why Selank has similar physiological effects as classical benzodiazepines.  Selank does not interact with GABA receptors the same way as benzodiazepines, but has very similar anxiolytic and antidepressant effects.  Thus, side effects such as abuse potential and tolerance, which are common with benzodiazepines, do not seem to occur with Selank.  It also modulates the expression of Interleukin-6 (IL-6), affects the balance of T helper cell cytokines, and influences the concentration of monoamine neurotransmitters and serotonin metabolism.


Numerous clinical studies have shown that Selank has strong antianxiety and neuroprotective effects in the treatment of generalized anxiety disorders.

Semax is a nootropic that is known for its neuroprotective and neurorestorative effects.   The neuroactive peptide possesses neurotrophic, neuroregulatory, and neuroprotective properties in the central nervous system.   Semax belongs to the melanocortin family of compounds which includes adrenocorticotropic hormone (ACTH) and melanocyte-stimulating hormone.   Semax is currently used clinically in Russia and Ukraine for treatment of cranial and head injuries like stroke and TBI, as well as for neurodegenerative diseases like Alzheimer's and Parkinson's Disease. In addition to its nootropic effects, Semax has also been shown to have anti-inflammatory, antioxidant, regenerative, vasodilatory, and neuroprotective properties.


Oxytocin is a nanopeptide hormone that plays a role in human behavior, including social bonding, love, reproduction, childbirth, and the period after childbirth. It's produced in the hypothalamus and released by the posterior pituitary.  Oxytocin is associated with functions that support a sense of safety, sociality, as well as survival and reproduction. It can induce anti-stress-like effects such as reduction of blood pressure and cortisol levels, and increases pain thresholds. Both men and women also release the hormone during skin- to-skin contact, sexual arousal, and orgasm/ejaculation. Moreover, oxytocin plays a major role in different human behaviors such as trust, bonding, desire, and social recognition. Because of this, oxytocin is called the “cuddle” or “love” hormone.

Selank safety profile

Selank has a high safety profile and is practically non-toxic since it breaks down in the body into amio acids.  Selank has been recommended by Russian and Ukraine doctors for more than a decade and is availalble in Russia as an over the counter medication, available without prescription.  Numerous clinical trials confirmed the safety of this peptide, which was found to not form a dependence and to be non-toxic even in doses 200-500 times higher than the therapeutic ones.

Selank does not cause drowsiness, lethargy, dull thinking, and other side effects associated with most medications used to treat neurological and mental disorders.  Selank does not cause addiction or withdrawal symptoms,

Selank is compatible with other medications

Selank is compatible to be used with various medications to treat cognitive and neurological disorders.   Selank has a positive effect when utilized in combination with other medications by alleviating withdrawal symptoms and reducing side effects.  Selank can be safely utilized along with consumption of alcohol and helps offset the toxicity of alcohol on brain function.

Semax safety profile

Research shows that Semax is very well-tolerated by most users, with few reported side effects. However, some users experience a slight burning sensation in the nasal passages or mild mucus membrane irritation after administration.  Most reported side effects are mild and transient.

  • Headaches

  • Nausea

  • Vomiting

  • Drowsiness

  • Hair Loss (Increased BDNF levels can promote hair loss in patients prone to baldness) 

Oxytocin safety profile

Oxytocin side effects are very uncommon. There have been some side effects associated with the use of this drug wherein the patient had one of the issues listed below at some point while being on oxytocin. However, these side effects weren’t confirmed to be associated with the treatment and could have been a coincidence and not related to the use of oxytocin. Despite this, it was listed as a side effect associated with oxytocin even though these associated side effects are very uncommon.

Side effects associated with oxytocin may include the following:

  • Blurred vision

  • Confusion

  • Increased blood pressure

  • Loss of appetite

  • Nausea

  • Stomach pain

  • Vomiting
