Storage & handling
Peptides are photo- and temperature-sensitive; handle per standard laboratory practice.
- Lyophilized storage: Keep the sealed vial cool, dry, and protected from light. For longer-term storage, freezing is standard practice for lyophilized peptides.
- After reconstitution: Refrigerate (approximately 2–8 °C) and follow your institution’s SOPs for aliquoting, handling, and disposal. Avoid repeated freeze–thaw cycles.
- Diluent not included: A suitable laboratory diluent and reconstitution supplies are not provided with this product.
- UV-resistant glass vial to help protect photo-labile peptides during storage.
- Tamper-evident seal to support chain-of-custody and inventory controls.
Why source Selank from Sports Technology Labs
Quality control across the research-peptide industry is inconsistent, and many suppliers do not publish third-party testing for their products. Independent verification of identity and purity is essential for reproducible research.
Verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry, with batch-linked COAs.
Freeze-dried into sterile, UV-resistant glass vials and packaged in the USA.
Supports chain-of-custody, label transparency, and batch-linked traceability.
Transparent business, standard payment methods, no misrepresentation.
What is Selank?
Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is a synthetic analog of the endogenous immunomodulatory tetrapeptide tuftsin (Thr-Lys-Pro-Arg), extended with a C-terminal Pro-Gly-Pro sequence that increases its stability and half-life relative to tuftsin.
It was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is used as a research chemical to investigate tuftsin-analog peptide biology in experimental models.
Selank is an experimental research chemical, supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding its effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
Important regulatory information
Selank is an investigational research peptide. It is not approved by the FDA and is not a drug, food, dietary supplement, or cosmetic. Marketing it for human use is unlawful.
Selank is not currently listed on the World Anti-Doping Agency Prohibited List.
In the United States, Selank is not a controlled substance and may be legally purchased and possessed for laboratory research use. Other jurisdictions may regulate it differently.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
