Research Overview

Desmopressin

The literature is mixed, but desmopressin has shown memory-related effects in selected populations and experimental paradigms. Its cognitive effects are usually discussed as a vasopressin-pathway probe rather than a primary nootropic.

Efinopegdutide

Human trials have shown meaningful weight loss and improvements in hepatic steatosis biomarkers. It remains a research compound with ongoing development in metabolic disease.
