What is Semax Selank blend?
This is a two-peptide blend with equal parts Semax and Selank. The 10mg vial has 5mg of each, and the 20mg vial has 10mg of each.
Semax (Met-Glu-His-Phe-Pro-Gly-Pro, about 813.93 g/mol) comes from the 4-10 fragment of ACTH. Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro, about 751.87 g/mol) is built on tuftsin, a piece of immunoglobulin G. Both were designed the same way: a native fragment with a Pro-Gly-Pro tail added so enzymes break it down more slowly.

What researchers study Semax Selank blend for
Semax and Selank are both Russian-developed peptides, and labs studying one often look at the other. The Semax Selank blend gives you both in a fixed 1:1 ratio. For research use only. Semax is listed on NIH PubChem.
How to store Semax Selank blend
Refrigerate at 36 to 46 °F (2 to 8 °C). Keep it cold after reconstitution.
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.
