Research Overview

Orexin-A

Preclinical studies link orexin signaling to arousal, learning, and memory consolidation, making orexin-A a candidate for cognition-related research. It is not an approved cognitive enhancer and remains an experimental peptide.

GLP-1(7-36) amide

One of the best-studied gut hormones, with strong evidence for incretin biology and appetite regulation. Native GLP-1 is rapidly degraded by DPP-4, which is why its biology is central to endocrine and metabolic pharmacology.
