5-Amino-1MQ
Dosage Protocol
5-Amino-1MQ is a small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme highly expressed in adipose tissue. By blocking NNMT, it elevates intracellular SAM (S-adenosylmethionine), shifts one-carbon metabolism, activates AMPK, and reduces adipocyte differentiation — producing fat loss without directly stimulating catecholamine pathways.
What is 5-Amino-1MQ?
5-Amino-1-methylquinolinium (5-Amino-1MQ) is a cell-permeable NNMT inhibitor developed at Weill Cornell Medicine. NNMT is overexpressed in obese adipose tissue and acts as a metabolic sink for methyl groups — its inhibition restores SAM levels, activates downstream AMPK and SIRT1 pathways, and suppresses adipocyte differentiation.
Preclinical data in diet-induced obese mice show significant reduction in fat mass and body weight without changes in food intake or lean mass, suggesting it targets fat specifically. Research suggests it may also enhance NAD+ metabolism and energy expenditure. It can be administered orally or subcutaneously, with most research protocols favoring oral capsule formulations for convenience.
Dosing Schedule
Parameters documented in published preclinical and clinical research.
| Phase | Dose | Frequency | Duration | Notes |
|---|---|---|---|---|
| Start | 50 mg | Once daily | Days 1–14 | Oral capsule. Assess GI tolerance and energy response. |
| Working dose | 50–100 mg | Once or twice daily | Weeks 2–8 | Most research protocols use 50 mg 2× daily or 100 mg once daily. |
| Stack | 50 mg | With NAD+ | Ongoing | Often stacked with NAD+ for synergistic metabolic and energy effects. |
| Off cycle | — | — | 2 weeks | Cycle off periodically to reassess response. |
