NNMT activity increases with age, obesity, and metabolic dysfunction
B12 (hydroxocobalamin) is a prescription-only medicine in the UK and is safest given by, or under the supervision of, a trained clinician
Neelakantan and colleagues (Biochem Pharmacol, 2017) then took the pharmacological step, reporting that selective, membrane-permeable small-molecule NNMT inhibitors reversed high-fat-diet-induced obesity in mice this is the study most directly relevant to the 5-Amino-1MQ class, because it moves from the target matters to a drug against the target does something in a live animal. And again, it is a mouse study
Some independent researchers recommend taking the full daily dose on an empty stomach, first thing in the morning
The NNMT-blocking mechanism of 5-amino-1MQ has been shown to increase levels of the cofactor NAD+, whose replenishment in organisms promotes muscular, cognitive, and immune function, as well as increased lifespan [4, 5]
Some research community protocols stack 5-Amino-1MQ with AOD-9604 or with a GLP-1 drug, but no human study has tested those combinations
