Product information
This blend contains two peptides in a single vial: 10 mg Semax and 10 mg Selank. Both are heptapeptides, chains of seven amino acids, but they have a different origin.
Semax is derived from a fragment of ACTH, a hormone produced by the pituitary gland. Research into Semax is mainly about attention and memory. Selank is derived from tuftsin, one of the body's own peptides from the immune system; research into that is mainly about anxiety and tension. Because the research into the two points in different directions, they are often placed side by side in the literature. Our comparison of Selank and Semax goes through the differences.
A third peptide in this field is P21. How to dissolve the powder with bacteriostatic water is explained in the reconstitution and storage guide. You can find the full range under Cognition & focus.

Frequently Asked Questions
What is in this blend?
10 mg Semax and 10 mg Selank, together in a single vial of freeze-dried powder.
What is the research into these two peptides about?
With Semax the focus is mainly on attention and memory. With Selank it is mainly on anxiety and tension.
Why are Semax and Selank offered together?
They have a different origin and the research points in different directions. That is why they are often placed side by side in the literature. In a single vial you only need to reconstitute once.
Are Semax and Selank approved medicines?
No. Neither substance is registered as a medicine anywhere. What we supply is intended solely for laboratory research.
What do you dissolve this blend in?
With sterile bacteriostatic water. It is included free with every vial. Let the liquid run down the wall of the vial and swirl gently rather than shaking.
How do you store this blend?
Unopened, store in a cool, dry, and dark place at 2 to 8 °C. For longer storage, -20 °C is suitable, only in powder form. After dissolving, store the vial refrigerated; the quality of the peptide deteriorates from approximately 30 days.
