Description
Selank 5mg from Evolve Peptides is 5mg of Selank in a sealed glass vial. Selank is a tuftsin analog peptide. It’s for in-vitro and lab research only.
About Selank
Selank is a seven-amino-acid peptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) based on tuftsin, with a Pro-Gly-Pro tail added. It was developed at the Institute of Molecular Genetics in Moscow.
It’s registered in Russia for anxiety.
Selank mechanism of action
Selank is based on tuftsin, a short immune peptide cut from antibodies. The Pro-Gly-Pro tail added at the end makes it more stable.
In rat studies it changed the expression of genes tied to GABA signaling and raised BDNF. It’s also studied for effects on the enzymes that break down enkephalins, the body’s own opioid peptides.

Selank 5mg reconstitution and concentration
The volume of water you add sets the concentration. For a vial holding 5mg:
- 1ml of bacteriostatic water gives 5mg/ml
- 2ml of bacteriostatic water gives 2.5mg/ml
- 3ml of bacteriostatic water gives 1.67mg/ml
Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label.
Use sterile bacteriostatic water. Warm the sealed vial to room temperature first so no condensation gets in, add the water slowly along the glass wall, and swirl gently until it’s clear. Never shake.
Storing Selank 5mg
Unopened, keep Selank 5mg in a fridge at 2 to 8°C, or in a freezer at -20°C if it’ll be a while before you use it. Keep it out of direct light. Once mixed, keep it refrigerated and use it within about 28 days, which is how long bacteriostatic water stays good after opening.
