What Are Selank and Semax?

Selank and Semax are synthetic peptides originally developed in Russia for their nootropic and neuroprotective properties. Both were created to support cognitive performance, improve mood, and reduce the negative effects of stress. While they share a similar background, each peptide works through different pathways and provides distinct benefits.

Selank is a synthetic variant of tuftsin, a peptide involved in immune regulation. It is primarily recognized for its calming, anti-anxiety effects, along with its ability to support brain health and stress resilience.

Semax, in contrast, is derived from a fragment of the ACTH (adrenocorticotropic hormone) molecule. It is widely studied for its cognitive-enhancing properties, particularly in areas such as focus, memory, and learning capacity.
