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(1-37)OH

Human GHRF(1-37)OH has appeared in studies examining how loss of C-terminal residues affects biological activity at the GHRH receptor. It is often used alongside other fragments to define structure-activity relationships within the GHRH family.
