Description
This is Selank, supplied by LA Peptides as 10mg of freeze-dried powder in a sealed vial. Every batch has its own certificate of analysis, and you can pull it up by scanning the QR code on the side of the label. It’s for laboratory research only.
What is Selank?
Selank is a synthetic heptapeptide: Thr-Lys-Pro-Arg-Pro-Gly-Pro. The first four amino acids are tuftsin, a natural immune peptide. The Pro-Gly-Pro tail was added to protect it from enzymes so it lasts longer.
It’s studied for anxiety and stress responses, and for its effects on immune signaling molecules.

What the research says
The Institute of Molecular Genetics of the Russian Academy of Sciences developed Selank, and it’s registered as a medicine in Russia. Most published studies come from Russian groups and look at anxiety, memory and the GABA system in rodents.
It isn’t approved in the US, and outside Russia it’s a research compound.

Checking the batch COA
Every batch gets its own certificate of analysis, and the QR code on the label takes you straight to it. Look for the lot number, the test date and the purity figure. If the lot on the paperwork doesn’t match the lot on the vial, set the vial aside until it’s sorted out.
File the COA with the rest of your study notes. If results ever shift between batches, it’s the first thing you’ll want to check.
Working out the concentration
How much liquid you add decides the concentration. For this vial holding 10mg:
- 1ml of bacteriostatic water gives 10mg/ml
- 2ml of bacteriostatic water gives 5mg/ml
- 3ml of bacteriostatic water gives about 3.33mg/ml
Choose whichever volume makes the math simplest for your protocol, and label the vial with the concentration and the mixing date.
Storing and mixing
Unopened, the vial is happiest in a fridge at 2 to 8°C, or frozen for longer storage. Let it warm up to room temperature before you break the seal, so condensation doesn’t get in.
Most labs reconstitute it with bacteriostatic water. Add it slowly against the glass, then roll the vial between your fingers until it clears. Shaking can damage peptide chains, so skip that. Refrigerate the mixed solution and use it within about a month. A peptide case helps if vials travel between benches.
