A synthetic peptide studied primarily in neuroscience research, including investigations into neurotransmitter signaling and behavioral pathways. Selank remains a compound of interest for exploring peptide activity within the central nervous system. For laboratory research use only.

Selank started as an immune fragment. Its first four residues, Thr-Lys-Pro-Arg, are tuftsin, a tetrapeptide cut from the heavy chain of IgG antibodies. Researchers at the Institute of Molecular Genetics in Russia added a Pro-Gly-Pro tail to slow its breakdown, giving the heptapeptide TKPRPGP. That hybrid origin explains why selank peptides turn up in two very different literatures: anxiety and memory models on one side, stress, gut and immune markers on the other.
The label is where buyers get caught out. N-acetyl Selank amidate is a separate compound with an acetyl group on one end and an amide on the other, roughly 41 Da heavier than the standard chain. Forum threads trade tips on which version is "better," but for a study, the version is simply part of the method. The market doesn't make it easy: some listings never print a sequence, and one seller lists a spring batch while displaying the report from an older one. Titan Core sells the standard, unmodified heptapeptide, made in the USA. Every batch goes to an independent lab for HPLC purity and mass spectrometry, and the report carries the same LOT as your vial. Selank is sold strictly for laboratory research and isn't for human or animal use.

A synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, built from the immune peptide tuftsin plus a stabilizing Pro-Gly-Pro tail.
In research, mainly anxiety-like behavior, memory, stress responses and immune signaling, studied almost entirely in rodents and cell models.
Both come from the same Russian institute and share a Pro-Gly-Pro tail. Selank builds on tuftsin, an immune fragment; Semax builds on a fragment of ACTH, a stress hormone.
This is standard Selank, with no acetyl cap and no amide. The two differ in mass, so the report's mass result against Product Details shows which you hold. If its LOT doesn't match your vial, contact support before opening it.
They share a design approach and a research home, so papers frequently compare them side by side, especially in anxiety and cognition models.
It has no FDA approval. Titan Core supplies it for laboratory research only and doesn't advise on selank side effects, dosing or use in people.
