Selank + Semax blend

Summary

This blend pairs the two Russian-developed heptapeptides, Selank (studied for anxiety) and Semax (studied for stroke and cognition). Both share the stabilizing Pro-Gly-Pro tail. There is no published research on the combination.

Components

• Tuftsin analog Selank Selank is a synthetic seven-residue analog of tuftsin, a fragment of immunoglobulin G. Early human data
• ACTH(4-10) analog Semax Semax is a seven-amino-acid peptide developed in Russia from a fragment of adrenocorticotropic hormone (ACTH). Early human data

How it works

Suppliers market the pair as covering both calming and cognitive effects, based on each peptide’s separate literature.

What the research found

Safety and open questions

Combining compounds can change how each behaves, and fixed ratios mean you cannot adjust one without the other. Component purity and identity are harder to verify in a blend, because a single certificate of analysis must confirm several peptides.
