Selank is a synthetic analog of the immune peptide tuftsin, studied for its anxiolytic and nootropic properties without sedation. It is a key compound in the stress and mood research category.

Buy Selank online from Healio. Selank for sale comes as a 10mg vial, supplied as a research peptide for laboratory use only and shipped from the USA with the batch certificate of analysis published before you order. You can order Selank straight from this page.

What is selank?

Selank is a synthetic analog of tuftsin, a naturally occurring immune-regulating peptide. It was developed in Russia and has been studied in relation to anxiety, stress response and cognitive performance.

Its distinguishing feature in the research literature is that it appears to modulate stress signalling without the sedation profile that characterises older anxiolytic compounds, which is what makes selank for sale a recurring search among researchers working on stress and cognition.

Selank research applications

Published research covers anxiety and stress response, cognitive performance, and immune modulation through its tuftsin lineage. There is also work on BDNF and neurotransmitter signalling, particularly serotonin.

The literature is moderate in size and shares the translation and replication caveats common to Russian-origin peptide research.

How selank works

Research describes several proposed mechanisms. One involves influence on GABAergic signalling, relevant to anxiety pathways. Another concerns effects on BDNF, a protein involved in neuron growth and survival. A third relates to serotonin metabolism.

The immune connection is structural rather than incidental: tuftsin, from which selank is derived, is itself an immune-regulating peptide.

Selank vs semax

Property Selank Semax
Derived from Tuftsin ACTH fragment
Research focus Anxiety, stress, immune signalling Cognitive, neuroprotective
General character Calming, stress-regulating Stimulating, cognitive
Stocked by Healio Yes No

We stock selank and not semax, and prefer to state that plainly rather than steer the comparison. Both are covered in the best peptides for energy.

Selank reconstitution and handling

Supplied lyophilized. Reconstitute with bacteriostatic water, adding diluent slowly against the vial wall and letting the powder dissolve without agitation. Bacteriostatic water is stocked separately. The Selank calculator turns vial strength and water volume into a concentration.

Selank storage and stability

Store sealed lyophilized vials at minus 20 degrees Celsius, protected from light. Reconstituted solution requires refrigeration and a shorter window. Avoid freeze and thaw cycles.

Selank price

Selank 10mg is $38.99 per vial, which works out to $3.90 per mg. Ordering more than one vial lowers the price of every vial in the order. The table shows the Selank price per vial and per mg for every size. That Selank cost is the price per vial before shipping. For the best price per vial on Selank, order three or more.

Where to buy Selank in the US

Where to buy Selank peptide matters more than the price, because a vial is only worth what its testing is worth. Five checks separate a reliable US supplier from a reseller, and this is how Healio meets each one.

  • A certificate of analysis for the exact batch. The Selank report for batch HEALIO-SLNK-2611 is published before you order, not emailed after you have paid.
  • Testing by a lab that is not the seller. The report comes from Quantum Life Sciences in Portland, Maine, an independent laboratory, and carries its own certificate number.
  • Identity as well as purity. HPLC measures how pure the powder is. Mass spectrometry (ESI-MS) confirms that it is Selank in the first place. A report with only one of the two is half a report.
  • A lot number you can trace. The lot number on your vial ties to its own report, so you can check the document against the product in your hands.
  • US dispatch and plain terms. Orders ship from the United States, and the shipping and returns policy is public before you buy.

Selank lab results

The current Selank batch was tested on 23 June 2026 by Quantum Life Sciences. The certificate covers the 10 mg vial. Purity is measured by HPLC and identity is confirmed by mass spectrometry. The summary below is taken from the certificate of analysis. Reading the Selank COA takes a minute: purity by HPLC, identity by mass spectrometry and endotoxins are in the first rows.

Selank reviews: is Healio a legit Selank source?

Searching for Selank reviews, or asking whether Healio is a legit Selank source? The useful evidence is what you can check yourself, because reviews only help if you can check them.

  • Match the lot number on your vial to the Selank certificate of analysis.
  • Look up the testing laboratory named on the certificate and confirm it is not Healio.
  • Read how the content on this site is written and checked on the editorial standards page.
  • If a seller will not publish a batch report for the product you are buying, treat that as your answer.

How do I reconstitute Selank?

Lyophilized Selank is reconstituted with bacteriostatic water. The Selank calculator converts vial strength and water volume into concentration and syringe units. It is arithmetic only and does not recommend an amount.

Is Selank for human use?

No. Healio supplies Selank strictly for laboratory research. It is not for human or veterinary use, and it is not a drug, supplement, food or cosmetic.

What is selank used for in research?

Anxiety and stress response studies, cognitive performance research, and immune signalling work through its tuftsin lineage. Supplied for laboratory use only.

How is selank different from semax?

Selank derives from tuftsin and research leans toward anxiety and stress regulation. Semax derives from an ACTH fragment and research leans cognitive and stimulating. Both come from the same Russian research programme.

Is selank sedating?

The research interest centres on modulating stress signalling without the sedation associated with older anxiolytic compounds, which is a distinguishing feature in the published work.
