Research Overview
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.
Kisspeptin-10
Kisspeptin-10 has growing clinical evidence. Multiple human studies demonstrate reliable GnRH stimulation and subsequent testosterone increase. Being actively studied for reproductive medicine, including IVF protocols and hypogonadism. Unique advantage of not suppressing the HPG axis.
