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.

hGHRH(1-40)OH

Human GHRF(1-40)OH has been studied to understand how truncation of the native hormone changes biological potency and half-life. It is a common research tool for mapping minimal active sequences within the GHRH family.
