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.
CJC-1295
CJC-1295 has good pre-clinical and early clinical data. The DAC variant shows sustained GH elevation for days. Often combined with GHRPs for synergistic GH release.
