Overview

About Semax / Selank Blend

The Semax / Selank Blend combines two seven-amino-acid peptides developed through research originating from the same Russian institute. Semax includes a fragment derived from ACTH along with a short stabilizing sequence that helps protect it from rapid enzymatic breakdown, and has been studied for its effects on BDNF and dopamine and serotonin signaling. Selank is derived from tuftsin, a naturally occurring immunomodulatory peptide, shares the same stabilizing C-terminal sequence, and has been investigated for its effects on GABA-related signaling and stress-associated behavioral and physiological endpoints.

FAQ

Common Questions About Semax / Selank Blend

What is the Semax / Selank Blend?+

A combination of Semax and Selank, two seven-amino-acid neuropeptides from the same research lineage, studied through complementary signaling pathways.

What is Semax?+

A seven-amino-acid peptide including an ACTH-derived fragment, originally developed by Russian researchers and studied for BDNF and dopamine/serotonin signaling.

What is Selank?+

A synthetic seven-amino-acid peptide derived from tuftsin, studied for GABA-related signaling and stress-associated endpoints.

Why combine these two compounds?+

They share a stabilizing structural sequence but act on different primary pathways (BDNF/neurotransmitter signaling vs. GABAergic modulation), making the pair useful for combined-pathway research.

Does Semax act like a stress hormone?+

No, despite being derived in part from ACTH, it has not shown the same stress-hormone activity in experimental studies.
