For laboratory research use only - not for human consumption

TKPRPGP tuftsin-analog study material

Selank

A synthetic heptapeptide studied in anxiety-related behaviour, BDNF, immune-marker, and GABA/serotonin research. Supplied for laboratory research only.

Your immune system makes a small peptide called tuftsin. It falls apart within minutes, which makes it nearly impossible to study. Selank is a Russian-designed copy, built to last long enough to work with. Supplied freeze-dried, for laboratory research only.

Why this molecule is studied

Why researchers are studying it.

Researchers got interested in Selank because it is a durable copy of something your own immune system already makes. Now the honest bit: most of that research is animal and laboratory work, plus clinical studies carried out in Russia, where Selank is prescribed and sold. It has never been assessed by the TGA in Australia or the FDA in the United States, and it has no EU marketing authorisation. The main human record here is a 2008 Russian study of 62 adults.

That thing your immune system makes is called tuftsin - a four-amino-acid peptide that breaks down almost as fast as it appears. Selank keeps tuftsin's four-piece core and adds a three-piece tail, which makes the molecule durable enough for researchers to actually work with. That is the whole design.

What the studies look at is mostly anxiety-related behaviour in animals, alongside things they can measure directly: BDNF, a growth signal for nerve cells, and the GABA and serotonin systems - two of the brain's main chemical messengers.

This page is about that research and the batch you are getting. The measurements described are laboratory and animal study endpoints, not effects in a person, and this is not for people or animals to take. Registry details (TP-7, CAS 129954-34-3) are in the FAQ below.

Mechanism notes

Plain-language research labels.

What it was copied from, and what the studies measure alongside it. These are animal and laboratory measurements - study endpoints, not effects claimed for this vial.

A copy of tuftsin, built to last

Tuftsin is a four-amino-acid peptide your immune system makes, and it falls apart within minutes. Selank keeps that same four-piece core - written TKPR - and adds a three-piece tail, Pro-Gly-Pro, that makes it much harder to pull apart. That durability is the entire point of the design: it is what let anyone study the sequence at all.

What BDNF is

A growth signal for nerve cells - it helps them survive, grow, and wire up new connections. Studies measure whether BDNF shifts after Selank because it is something a researcher can read directly rather than infer.

GABA and serotonin

Two of the brain's main chemical messengers. GABA is the quieting one: it dials nerve signalling down. Serotonin is involved in mood and sleep. Papers report Selank alongside measurements of both, which is why it appears in anxiety-related behaviour research.
