Description
What Is Selank 10mg? (In Plain English)
Selank is a short chain of seven amino acids copied from a tiny natural peptide called tuftsin, with a small tail added on the end. That tail works like a plastic tip on a shoelace: it keeps the molecule from fraying so quickly. Researchers study Selank in rodents to see how that longer-lasting signal affects brain chemistry and calm-versus-alert behaviour.
Selank 10mg — Research Overview
Selank is a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, formed by extending the endogenous immunomodulatory tetrapeptide tuftsin (TKPR) with a C-terminal Pro-Gly-Pro sequence that markedly slows enzymatic degradation. Developed at the Institute of Molecular Genetics in Russia, it is referenced in the literature as a regulatory peptide acting without receptor-level hormone activity. Reported research associations include GABAergic and monoaminergic modulation, effects on BDNF expression in rodent hippocampus, and inhibition of enkephalin-degrading enzymes.
Primary Research Areas
- Anxiety-related behavioural models — elevated plus maze and open field paradigms in rodents
- Neurotrophic signaling — BDNF and related gene-expression changes measured in rodent brain tissue
- Monoamine and GABA systems — serotonin turnover and GABA-A receptor gene expression in animal studies
- Enkephalinase inhibition — studied for its association with slowed enkephalin breakdown in plasma
- Immunomodulation — carried over from the tuftsin parent sequence and examined in cytokine assays

Related Research Peptides
Selank is most often studied alongside Semax 10mg, the other Pro-Gly-Pro-stabilized Russian regulatory heptapeptide, and the two are frequently run in the same behavioural panels. Neuro-focused laboratories also reference P21 5mg, DSIP, and PE-22-28 when building comparative study designs.
Why Researchers Source Selank 10mg from Dissolv Labs
Dissolv Labs is a research-supply company based in Southern California. Orders are picked, packed, and shipped domestically from our SoCal facility, so most U.S. laboratories see short transit times and no international customs delay.
Every vial ships as a complete kit. Each Selank 10mg vial is paired with its own bacteriostatic water reconstitution vial, so the material arrives ready to prepare in the lab without a separate diluent order. Compounds are supplied lyophilized in sealed, labeled vials with lot identification, and analytical documentation is available on request.
Selank 10mg — Frequently Asked Questions
What is Selank 10mg used for?
Selank 10mg is supplied strictly as a research chemical for in vitro and laboratory research applications. The literature investigates it in rodent behavioural models associated with anxiety research, and in studies of BDNF expression and monoamine turnover. It is not for human or veterinary use.
Selank vs Semax — how do the two differ?
Both are synthetic heptapeptides stabilized by a C-terminal Pro-Gly-Pro extension, but their parent sequences differ: Selank derives from the immune tetrapeptide tuftsin, while Semax derives from the ACTH(4-10) fragment. As a result the literature associates Selank more with GABAergic and anxiety-related behavioural endpoints, and Semax more with attention, memory, and neuroprotection paradigms. Many groups study them in parallel for exactly that contrast.
How is Selank supplied and stored?
Selank ships as a 10mg lyophilized powder in a sealed, lot-labeled vial, packed together with its own bacteriostatic water reconstitution vial. Lyophilized material is kept cold and protected from light, and reconstituted solution is stored refrigerated per standard laboratory practice. Short peptides of this class are generally handled promptly after reconstitution.
Where can I buy Selank research peptide?
Dissolv Labs supplies Selank 10mg to qualified researchers, shipping domestically from our Southern California facility for short U.S. transit times. Each order arrives as a complete kit with the reconstitution vial included. Analytical documentation for the supplied lot can be requested with the order.
Research Use Only
Selank 10mg is sold exclusively as a Research Use Only (RUO) chemical. It is not a drug, supplement, cosmetic, or food, and it is not intended for human or veterinary use, ingestion, injection, topical application, or any form of consumption. It is intended solely for licensed laboratory research by qualified professionals. Dissolv Labs makes no medical, therapeutic, or diagnostic claims of any kind. By purchasing, the buyer confirms they are a qualified researcher and accepts full responsibility for lawful handling, use, and disposal.
Bacteriostatic (BAC) water is included free with every order.

Exact quantity and concentration are listed in the product title and variant options above. The figures above are release specifications — the measured result for your particular lot is stated on its Certificate of Analysis.
Documentation & Testing
Every batch is tested before release. Testing covers four checks: identity by mass spectrometry, purity by HPLC against a ≥99% release threshold, content verification against the labelled mass, and batch release tied to a specific lot number.
To request the Certificate of Analysis for your vial, email us with your order number or the lot number printed on the label. We do not gate documentation behind a form or a purchase.

Handling & Storage
Lyophilized peptides are relatively stable during transit. Arriving at room temperature is not cause for concern — the cold pack is a margin of safety rather than a pass/fail condition.
Sealed vials of lyophilized material are typically stored refrigerated or frozen and protected from light. Handling protocols for a specific compound are determined by the researcher and their institution; we supply the material and its documentation.
Shipping & Returns
Orders placed before the daily cut-off are dispatched the same business day from Southern California in insulated packaging with ice packs. Tracking is issued at dispatch.
If a shipment arrives damaged, if vial contents appear inconsistent with the specification, or if the lot number on your vial does not match the certificate we provide, contact us and we will resolve it.
Because these are temperature-sensitive laboratory materials, opened vials cannot be returned to stock.
