Description
The Selank 10mg 12 pack from Oath Peptides gets you 12 vials of Selank 10mg for $624, or $52 a vial. Selank is a seven-amino-acid tuftsin analog (CAS 129954-34-3) supplied as freeze-dried powder.

What is Selank?
Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, first described in the late 1990s. It’s built on tuftsin, a natural four-residue piece (Thr-Lys-Pro-Arg) of the immunoglobulin G heavy chain. The designers added a Pro-Gly-Pro tail, the same one used on Semax, to slow down breakdown.
Its formula is C33H57N11O9 and its weight is 751.87 g/mol. You might also see it called TP-7 or Selanc. Tuftsin on its own breaks down fast in solution. Selank holds up much better.

What researchers study Selank for
Like Semax, Selank came out of Russian research, and much of the published work looks at anxiety and stress models in rodents. It’s for lab research only. See NIH PubChem.
How to store Selank
Store refrigerated at 36 to 46 °F (2 to 8 °C). It dissolves readily in water. Keep it cold once mixed.
Most labs reconstitute with Research Water, which is sterile-filtered water with 0.9% benzyl alcohol.
When it’s time to reconstitute, let the vial come to room temperature first. Add the solvent slowly down the inside wall of the vial so it doesn’t hit the powder directly, then swirl gently until the liquid is clear. Don’t shake it. Write the date on the label so you know how long it’s been mixed.
