About this compound
Selank
Tuftsin-analogue heptapeptide
Half-life
≈ minutes (peptidase-dependent)
Selank is a synthetic heptapeptide analogue of the immunomodulatory peptide Tuftsin, developed at the Institute of Molecular Genetics. It is widely used as a tool compound across anxiety-, cognition- and neuroimmune-research models, particularly for probing GABAergic tone and BDNF-related signalling in pre-clinical assays.
Selank is examined in vitro for its influence on GABAergic signalling, BDNF expression and neuroimmune pathways.

Selank is a synthetic analogue of the endogenous immunomodulator tuftsin, supplied by MyPeptides for laboratory research use only.
Selank is a synthetic analogue of the endogenous immunomodulator tuftsin. MyPeptides supplies it as a lyophilised 5 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Selank in anxiolytic-signalling and neuropeptide research. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Selank order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. Adds a Pro-Gly-Pro tail to tuftsin for improved stability in the studies that cite it.

Reference-grade quality
Ordered late Monday, arrived Wednesday morning in the UK. Packaging was cold-protected and every vial sealed correctly. CoA matched the batch number on the label.

Quality packaging, quick dispatch
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
