Research Overview
5-Amino-1MQ
Studies in diet-induced obese mice showed significant reductions in body weight, white adipose tissue mass, and cholesterol levels without changes in food intake. Works by inhibiting NNMT enzyme to increase NAD+ and activate sirtuins.
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.
