Description

Selank Peptide

Selank is a small peptide studied for its potential nootropic and anxiolytic characteristics. It is a synthetic analog of naturally occurring Tuftsin, an immunomodulatory peptide regulating T helper cells, IL-6, monoamine neurotransmitters, and brain-derived neurotrophic factor (BDNF). Selank differs in structure from the endogenous Tuftsin by the additional four amino acids in its chain, which have been supposed to enhance the metabolic stability and half-life of the synthetic peptide.

Selank Research

Selank and GABA Neurotransmitters
As per Dr. Anastasiya Volkova of the Institute of Molecular Genetics in Russia, “numerous clinical studies have [suggested] that Selank has strong antianxiety and neuroprotective effects in the [context] of anxiety. Selank and classical antianxiety [compounds] such as benzodiazepine have a similar mode of action. Selank allosterically modulates GABAA receptors and increases the inhibitory action of GABA.” Researchers like Dr. Volkova have suggested that as a result of peptide activity, stress hormone levels may reduce. Studies focused on small concentrations of Selank exposure have reported a sedating effect similar to benzodiazepines. However, unlike the latter, it appears to be neither habit-forming nor leading to symptoms of withdrawal or amnesia. It has been suggested to influence the expression of 7 genes, moderately affect the expression of 45 other targets, all from a set of roughly 84 genes considered to be involved in GABA signaling.[1] The researchers reported that their “results showed that Selank caused a number of alterations in the expression of genes involved in neurotransmission.” They suggested the peptide may stimulate gene expression in neurons and influence affinity of GABA receptors for GABA. Synergism between Selank and benzodiazepines and other GABA receptor agonists appears to be mediated through alteration of the receptor affinity. Research in rats observes that Selank and benzodiazepines, when alone, appear to have similar impacts on stress hormones, particularly in the case of generalized anxiety disorder. The combined introduction of the two may address unpredictable chronic mild stress, despite Selank’s potential to be better equipped than benzodiazepines. The synergistic potential of these compounds has not been ascertained.[2] The impact of Selank on enkephalin degradation appears to modulate its influence on GABA receptors to a certain extent. Studies have suggested enkephalins with shorter blood stability is present in models of anxiety and phobic disorders. This is apparently caused by increased enkephalinase activity in blood, which may degrade the enkephalins. Studies in murine models of anxiety posit that the peptide appears to inhibit enkephalinase, stabilize enkephalins, reset the enzymatic pathway, and thus may preserve natural anxiolytic peptides.[3]

Selank Peptide and the Immune System in Anxiety
Selank has been studied for its potential to inhibit the gene responsible for the production of the inflammatory cytokine IL-6 in research models of depression, but not in control models.[4] Researchers also note that “the adaptogenic properties of selank may be beneficial [in the cases of exposure] to environmental stressors for the prevention of infectious diseases.” Thus it may be useful in models of anxiety-asthenic disorders, severe anxiety, fatigue, headache, heart palpitations, high blood pressure, nerve pain, and depression. Compared to standard anxiolytic compounds, like benzodiazepines, Selank research suggests it may improve asthenic symptoms such as fatigue and pain perception.[5] This may be due to its apparent stabilization of enkephalins and modification of expression of IL-6. The peptide appears to affect expression of nearly 34 genes in the inflammatory pathway including those affecting chemokines, cytokines, and receptors. Specifically, it has been studied in relation to Bcl6 expression which is considered to promote immune development. This scientific study not only helps to reveal the complex biological impact of the peptide but also may improve our understanding of the immune system. Selank and its truncated versions may mediate transient gene expression for C3, CAsp1, Il2rf, and Xcr1 in the mouse spleen. Selank may therefore alter the balance of the immune system and thereby modulate inflammation.[6]

Selank Peptide and Memory, Learning
Anxiety and learning/memory show a strong inverse association. The peptide appears to reduce the impact of anxiety on cognitive function. Selank research has suggested that the peptide may improve memory traceability and storage in rats.[7] This improvement was independent of the anxiety levels of the rats. The peptide appears to trigger better memory recall through the hippocampal expression of 36 different genes. The majority of the targets are membrane-associated proteins and regulate ion movement across cell membranes. Thus the ion-dependent processes in learning and memory appear to be enhanced by the molecule. Selank researchers have posited its potential towards helping in easy formation and access of memories. It may also help to rescue memory and cognitive abilities after injury in rats exposed to neurotoxins. This inference is considered to be due to the apparent inhibition of catecholamines in the brain.[8] Selank may thereby assist in restoring cognitive function after an injury.

Selank Peptide and Pain Perception
Enkephalins are natural peptides that are considered to reduce the severity of pain by interacting with opioid receptors. Their levels appear high in the brain and adrenal glands during the stress response. Selank may potentially reduce the levels in the brain, which may thereby surpress stress response.

    I work as an assistant tech in a lab at my local university and my professor and I were very pleased with the results.

  2. Levi Morris

    Such a great selection and very fair prices.

  3. Landon Gibson

    honestly I was a bit skeptical ordering these kinds of products from the internet as I usually get it from a compounding pharmacy but i am thoroguhly impresed.

  4. Theo McLean

    Very easy ordering and checkout process

  5. Li Westenfelt

    I can’t wait for my package to get here. Thank you guys for a smooth process

  6. River Brooks

    Without a question, the top website for peptides in the industry. Service was great! products were the best quality i’ve come by. Would recommend to others!

  7. Levi Morris

    You guys were able to refund my order in full, Thanks for that. They do stand by their word. I had placed an order for Selank and typically they get this all sent out and delivered within a few days of placing the order. This time around I never got an e-mail stating my peptides have been shipped or even preparing to be delivered. A few days went by and I e-mailed them to ask about my missing peptides. Turns out they were out of stock and someone forgot to e-mail me informing me of the issue. They offered a full refund or to send out the order once they get it in but I went with getting my money back.

  8. James Chan

    I feel like they are a solid peptide company. No hitches!

    After testing out a few different sellers and Biotech, I have concluded that biotechs service and peptides are by far the best for me and my needs. Prices are not too bad and overall good company.

  17. Briar Castillo

    Biotech is my favorite peptide supplier. Never had a time where what I needed was out of stock.

  18. Loyd williamson

    I have not had a bad experince with Biotech. The peptides meet my standards.
