Selank - Xeno Laboratories

Buy Selank by Xeno Labs at XSteroids. Selank is the seven amino acid peptide that Russian pharmacology developed as a synthetic analog of tuftsin; Xeno Labs packs it as a lyophilised powder in one vial. This page explains what is in the vial, what the published pharmacology says, the mixing arithmetic behind a U-100 syringe, and how the licensing and anti-doping position actually looks.

Selank has held a medical registration in Russia for decades, so away from that region the realistic form is a research vial of this kind. Nothing on this page is medical advice, and the amounts quoted are research figures rather than a regimen for a person.

What the Xeno Selank Vial Delivers and What You Are Buying

A single glass vial of lyophilised Selank is what arrives. The molecule counts seven residues, sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, a mass of about 752 g/mol, CAS number 129954-34-3 and PubChem identifier 11765600. It was designed at the Institute of Molecular Genetics in Moscow as a synthetic relative of human tuftsin, the immunomodulatory tetrapeptide.

The label from Xeno Labs carries the peptide name together with its strength, and the vial occupies the cognitive shelf next to Semax, the other compound to emerge from the same Moscow institute. No filler breakdown appears on the pack, no third party test of the contents has ever been published, and no human half-life can be quoted: one vial, one stated strength, exactly as labelled.

How Selank Works in Published Research

Selank modulates interleukin-6 expression and shifts the balance of T-helper cytokines. In rats it changes the concentration of monoamine neurotransmitters and the metabolism of serotonin, and it raises BDNF in the hippocampus quickly after administration. Together with Semax it also inhibits the enzymes that break down enkephalins and other regulatory peptides, with an IC50 of roughly 10 micromolar.

Behavioural work in animals shows antidepressant-like and anxiolytic-like activity, including in models of depression and anhedonia. The clinical literature, which is largely Russian, describes an anxiolytic effect without sedation and without the memory impairment seen with benzodiazepines at comparable doses, which is the single most quoted difference.

What to Expect from Selank Research

Expect a subtle, non-sedating profile in the animal and small clinical reports rather than a strong drug effect. The comparison papers position it against benzodiazepines and barbiturates, and the reported selling point is calm without a knockout, with cognition left intact. That is the claim; independent Western replication is thin.

Expect rapid onset in animal models, where BDNF rises quickly, and expect the human evidence to stay small. There are no large Western registration trials, no published human pharmacokinetics and no data on long term use, so the honest position is that the pharmacology is better described than the clinical outcome.

Selank Dosing, Mixing and Intranasal Arithmetic

For any lyophilised peptide the calculation never changes: the mass in the vial divided by the millilitres of water added gives the concentration, and each unit on a U-100 barrel equals one hundredth of a millilitre. If the material is wanted for intranasal work, the liquid is used as it stands and no further arithmetic is needed.

Worked Examples

Start from a 5 mg vial: adding 2 ml of bacteriostatic water yields 2.5 mg per ml, which puts 250 mcg into a tenth of a millilitre, read at the 10 unit mark. The identical 5 mg vial diluted with 5 ml becomes 1 mg per ml, so 100 mcg occupies that same tenth and the barrel again shows 10. A larger 10 mg vial with 5 ml lands at 2 mg per ml, putting 200 mcg in the tenth at 10 units. Substitute whichever strength your Xeno pack states.

Amounts Seen in the Literature

The Russian clinical route is intranasal, using a diluted solution three times a day for around 14 days. Vendor research figures sit near 250 to 500 mcg per intranasal dose, and the same range is sometimes quoted for subcutaneous work. Neither figure is a human dose recommendation.

Stacking Selank With Other Cognitive Vials

Selank is usually discussed next to the other cognitive peptide of the same origin, Semax, because the two share a research tradition and are frequently studied together. Recovery-minded buyers add the repair peptide BPC-157, and the same line keeps a longevity entry, Epitalon.

The metabolic vials answer a different question: Semaglutide and Tirzepatide. Hormonal support lives on a separate shelf, the HCG 5000 IU and HMG 75IU vials plus the SERM pair, Tamox and its partner Clomiphene. Nothing listed above is a suggested combination.

Breaks, Tolerance and Recovery Around Selank

No tolerance data exists for Selank in humans, because the long term studies were never run. Russian clinical use is described as short courses of about two weeks, which is a reasonable research convention: a defined block, notes on what was taken, then a gap before any repeat.

Selank has no connection to the androgen axis and is not suppressive, so it asks for no recovery protocol by itself. If someone runs it while a steroid cycle is going, the post-cycle thinking belongs with the steroids, and this catalog files the SERM and HCG entries for precisely that job.

Selank Side Effects, Status and WADA Rules

The reported clinical profile is mild: no sedation and no memory impairment at the doses studied, which is precisely how it was differentiated from the benzodiazepines. The limit is sample size and geography. Outside Russia the product is not sold as a pharmacy item, so the vial is the practical form.

Status, stated plainly: in Russia Selank holds licences for generalised anxiety disorder, for neurasthenia and as an immunomodulator, and that is the standing it carries in the literature. Where anti-doping is concerned, the WADA prohibited list omits Selank altogether, which reflects missing data rather than a clearance. This vial is a research product.

Storing the Selank Vial

The powder stays cold, refrigerated between 2 and 8 C, or held at a steady 15 to 25 C well out of the light, and the dry vial must never go into a freezer. After water is added the vial belongs in the fridge and the solution should be used up inside 28 days, thirty at the very outside; it is repeated freezing and thawing that damages it. Write the mixing date on the label. Draw each dose with a clean needle, keep the vial standing upright, and dispose of anything that has been left out overnight instead of returning it to the cold, because the peptide is what suffers.

Why Buy Selank from XSteroids?
