Research Overview
GHRP-2
GHRP-2 has strong clinical evidence. Approved in Japan for diagnostic use. Multiple human studies confirm reliable GH stimulation with a favorable side effect profile compared to GHRP-6.
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.
