Selank has been studied for its activity across multiple neurological and immunological pathways:
- Exhibits anxiolytic activity in animal models without sedative side effects seen with benzodiazepines
- Upregulates BDNF and GABA expression in cortical neuron studies
- Modulates IL-6 and other cytokine levels in immune pathway research
- Demonstrates neuroprotective effects against oxidative stress in cell culture models
- Enhances working memory and attention parameters in behavioral studies
Every batch of Selank is independently tested by a US-based third-party laboratory. Our Certificate of Analysis confirms:

common questions.
Everything you need to know about Selank for your research. Can't find an answer? Contact our team directly.
Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic analogue of the endogenous immunomodulatory peptide tuftsin. It has been shown in preclinical models to stabilize enkephalins, modulate GABA-A receptor activity, and upregulate BDNF expression — properties associated with anxiolytic and nootropic effects in laboratory settings.
Reconstitution parameters vary by study model. Researchers typically reconstitute with sterile bacteriostatic water. We recommend consulting peer-reviewed literature for protocol design. We do not provide dosing guidance for human use.
No. All products sold by Clean Labs USA are strictly for laboratory and in-vitro research use only. They are not drugs, supplements, or food products and are not intended for self-administration or therapeutic use. Purchase constitutes agreement to our Research Use Only terms.
Every order ships with a batch-specific COA. You can also search our full COA library at trycleanlabs.com/coa-library. COAs include HPLC purity data, mass spec confirmation, and endotoxin results.
Store lyophilized Selank powder at −20°C in a sealed vial, away from light and moisture. Shelf life exceeds 24 months under these conditions. Once reconstituted, store at 4°C and use within 28 days. Do not freeze reconstituted solution.
