Selank + Semax dissolving strips

What is it for?

Both compounds in one film. Selank derives from tuftsin and Semax from ACTH (4-10); they share only the proline-glycine-proline tail that stabilises them, which is why they are so often studied as a pair. In a combined strip the ratio is fixed at manufacture — the single-compound vials remain the right choice where that ratio is a variable, and the Selank and Semax comparison sets out how the two differ.
