SemaxWell Studied

Synthetic ACTH Analog | Nootropic & Neuroprotective Peptide

Semax is a synthetic peptide derived from the adrenocorticotropic hormone (ACTH) that has been investigated for its potential neuroprotective and cognitive-enhancing effects. Research suggests that Semax may influence various biological pathways, including neuroinflammation and intracellular calcium dynamics.
