Description
Selank: Research Compound Overview
Selank is a research compound supplied by Stimulus Labs for laboratory and in-vitro use. It is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro), an analog of the endogenous immunomodulatory tetrapeptide tuftsin extended with a Pro-Gly-Pro sequence to improve stability. It is studied in anxiolytic and cognitive-function research, with proposed effects on GABAergic signaling and neurotrophic factor expression. Molecular formula C33H57N11O9; molecular weight approximately 751.9 g/mol. Supplied as a lyophilized powder.
It is offered at 99%+ purity, with every batch independently verified by third-party HPLC and mass-spectrometry testing before listing, so researchers can trust the identity and purity of the material they receive. Stimulus Labs works only with laboratories that document their methodology, and re-tests new supplier lots before they reach the catalog, rather than relying on a single certificate provided at the point of manufacture.
Purity, Testing & Handling
Every batch ships with a batch-specific Certificate of Analysis (COA), confirming identity and purity ahead of listing, and available to view before you buy. Researchers should store the lyophilized powder at the temperature indicated on the vial label, reconstitute only with an appropriate diluent such as bacteriostatic water, and handle it exclusively within a controlled laboratory setting using standard aseptic technique. Once reconstituted, solutions are generally less stable than the lyophilized form, so researchers typically prepare only the volume needed for near-term use and record storage conditions as part of their protocol.

Chemical Identity
Selank is associated with CAS number 129954-34-3. Researchers can cross-reference this number against the CAS Common Chemistry registry to independently confirm identity rather than relying on any single supplier’s labeling. Keeping a record of lot numbers, COA results, and CAS verification alongside any published research is good practice for maintaining a reproducible research record.
For Research Use Only. Not for human or veterinary use. Not a drug, food, or cosmetic. Selank is sold exclusively to qualified researchers and institutions for laboratory research purposes, and Stimulus Labs makes no claims about outcomes outside of a controlled research setting.
