Research Overview
Neuropeptide S
Animal studies suggest NPS can reduce anxiety-like behavior while altering wakefulness and alertness through the NPS receptor system. Human cognitive data are very limited, and it has no approved clinical indication.
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.
