Regulatory Watch
5-Amino-1MQ (5-amino-1-methylquinoline) is a small molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme involved in cellular metabolism and energy homeostasis. It has been promoted in biohacking and fitness communities as 'exercise in a pill' based on preclinical studies showing reversal of diet-induced obesity in mice. There are no published human clinical trials. The compound is not FDA-approved for any indication and is sold only as a research chemical.
