SELANK (The Limitless Peptide)


SELANK (The Limitless Peptide)


Selank is an anti-anxiety compound that improves learning and increases energy without side effects or the risk of addiction.

Product Description

“Some peptides have demonstrated a remarkable skin-soothing effect, while others can improve the appearance of wrinkles, loss of firmness, and even help to soften the look of expression lines.”

Peptides even have incredible positive effects on many mental health problems and the ability to learn.

Take ‘ Salank’ the peptide nicknamed Limitless with the ability to increase learning

Selank is a small protein produced in Russia to treat anxiety and improve learning. No side effects have been observed. Keep reading to learn more about the possible benefits of Selank

Selank is an anti-anxiety compound that improves learning and increases energy without side effects or the risk of addiction.


Selank is small and only a fraction of the size of most naturally occurring proteins. It was derived by combining the sequence of a peptide called tuftsin with another sequence that improves its stability. Tuftsin is naturally occurring and makes up one part of IgG (an antibody) [R].

Rats were given tuftsin, and more recently Selank exhibited reduced anxiety and increased serotonin levels [R].

Selank (TP-7) Mechanism of Action

Selank stabilizes enkephalins in the blood. Enkephalins are natural peptides in the body that reduce stress

However, some mice did not demonstrate the enkephalin stabilization following dosing with Selank and did not benefit from its anti-anxiety effect [R].


In cells, Selank binds to GABA receptors. Most compounds that bind to GABA receptors cause a sedative effect. In mice treated with Selank, researchers discovered more activity in inhibitory neurons, which rely on GABA. This resulted in less brain activity

In addition, researchers discovered an increase in BDNF, which has been implicated in learning and memory and may explain how Selank improves learning

Selank also changes levels of the neurotransmitters norepinephrine, dopamine, and serotonin. They are involved in motivation, focus, and pleasure [R].

In some mice, Selank increased norepinephrine, but decreased dopamine and serotonin. In other mice, Selank increased norepinephrine and dopamine and did not change serotonin [R]. Therefore, its exact effect/mechanism is not clear.

effects (drowsiness and memory loss) [R, R].

In mice, Selank reduced their anxiety. The more anxious the mice were, to begin with, the more significant the result [R, R].

Additionally, it showed anti-anxiety effects on rats over 4 weeks of daily treatment [R].

In one study, researchers gave Selank supplements to rats with toxin-induced brain damage. This drug restored their brain activity to normal levels [R].

Selank protects cells from some viral infections. However, mice infected with a virus did not benefit from Selank (no treatment effect) [R].

IncreaseAntioxidant Activity in the Liver

Injection of Selank increased the levels of antioxidants in the livers of stressed mice [R].

Improve Symptoms of Depression

Mice treated with antidepressants, such as lithium, move more when placed in a forced swimming container [R, R].

Low doses of Selank were more effective at decreasing depression symptoms than high doses [R].

Selank is sold in three forms. The commonly researched form is Selank. NA-Selank (also called N-Acetyl Selank) is the same as Selank but with an “acetyl” group attached to one end.

Acetyl groups may assist in penetration into the brain [

No human studies have been performed on NA-Selank.

Amidate (also known as Etomidate) is a sedative used for general anaesthesia [R].

There are no available studies that combine Selank with Amidate.

Selank vs. Semax

Much like Selank, Semax is also a synthetic peptide.

Semax comes from a different protein (a brain hormone) and also has different purposes, such as improving circulation and preventing liver damage.

Dosage of Selank

Selank products are normally available as a 0.15% spray, with 75 μg of Selank per spray. The recommended dosage is 2 or 3 sprays per dose with 3 doses per day (a max total of 675 μg/day) [R].

For an adult weighing 67.5 kg (about 149 lbs.), this translates to about 0.01 mg Selank/kg body weight. Rat studies normally used 0.3 mg/kg body weight.

Limitations and Caveats

In sum, the above data seems encouraging, but there is room for scepticism about the future of Selank.

Firstly, despite the stabilizing protein sequence, the half-life of Selank is only two minutes. Selank is undetectable in the blood after 10 minutes [R, R

This puts into doubt whether it can really have the week-long effects as reported in the clinical trials.

There is limited information about Selank’s activity in patients because there are only 3 clinical studies listed in PubMed [R].

Another concern is the lack of reported side effects. Many of the studies conducted were very short-term (within 24 hours). More rigorous and longer testing must be performed to measure side effects.

One final concern is that Selank cannot be taken orally because the stomach will digest it. Thus, you must either inject it under the skin or inhale it through the nose, with inhaling being more effective in delivery to the brain [R].

This dosing requirement may be off-putting to some considering trying this drug.

While Selank is purchasable in Russia, it still has a long road ahead before it becomes readily available in the US. Synthetic peptides require FDA approval in the US.

The Russian Academy of Sciences reported all findings described above. As the Russian Academy of Sciences is the sole developer of Selank, there is a conflict of interest in these studies.
