  • Rare: Numbness in extremities

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.

Hexarelin

Hexarelin has extensive pre-clinical and clinical evidence. Multiple human studies confirm potent GH release. Unique cardioprotective properties are well-documented. Note that receptor desensitization limits long-term continuous use.
