5-Amino-1MQ
WellnessAlso known as: 5-Amino-1-methylquinolinium, 5A1MQ
Limited EvidenceWhat is 5-Amino-1MQ?
A small molecule NNMT inhibitor that has gained popularity in biohacking and weight-loss communities for its potential to boost cellular energy expenditure and reduce fat accumulation. Technically not a peptide, but widely discussed and sold alongside peptides in the metabolic health space.
How it works
Inhibits nicotinamide N-methyltransferase (NNMT), an enzyme that is overexpressed in fat tissue and linked to obesity. NNMT normally depletes SAM (S-adenosylmethionine) and NAD+ — two critical metabolic cofactors. By blocking NNMT, 5-Amino-1MQ is proposed to increase intracellular NAD+ and SAM levels, boosting energy expenditure and reducing fat cell size and lipogenesis.
What marketers claim
- ▸melts fat without diet or exercise
- ▸the next generation of weight-loss compounds
- ▸boosts metabolism naturally
- ▸reverses metabolic damage from obesity
What evidence supports
- ✓NNMT inhibition reduced body weight and fat mass in diet-induced obese mice
- ✓cell studies show NNMT inhibition increases NAD+ levels and energy expenditure in adipocytes
- ✓NNMT is overexpressed in adipose tissue of obese individuals (validated target)
- ✓structurally well-characterized NNMT inhibitor with documented selectivity in biochemical assays
Research evidence
Key studies on 5-Amino-1MQ, summarized in plain language. This is not an exhaustive list — it highlights the most relevant findings.
NNMT inhibition with 5-amino-1MQ reduces diet-induced obesity in mice
Finding: Treatment with 5-Amino-1MQ for 11 days reduced body weight by ~7% in diet-induced obese mice without affecting food intake. Fat mass decreased while lean mass was preserved. Adipocyte size was significantly reduced.
Limitation: Mouse study only. Short treatment duration. No assessment of long-term safety or effects on NNMT's other biological roles.
Antisense oligonucleotide knockdown of NNMT reduces body weight in obese mice
Finding: Reducing NNMT expression in fat and liver tissue of obese mice increased energy expenditure and improved insulin sensitivity. Demonstrated that NNMT is a viable anti-obesity target.
Limitation: Used genetic knockdown, not the 5-Amino-1MQ compound. Established target validity but not compound-specific evidence. Mouse model only.
Structure-activity relationship of NNMT inhibitors including 5-amino-1MQ
Finding: 5-Amino-1MQ demonstrated potent and selective NNMT inhibition in biochemical assays with good cell permeability. Well-characterized binding mode and selectivity profile.
Limitation: Biochemical and cell-based assays only. Selectivity against related methyltransferases was tested but in vivo off-target effects were not assessed.

What to expect
Realistic timeline based on available research. Individual results vary.
Week 1-2
No established human timeline. Mouse studies showed measurable changes in body weight and adipocyte size within 10 days of treatment.
Week 4-8
Anecdotal reports from early adopters mention reduced appetite and modest fat loss. No controlled human data to validate these reports.
Month 3+
Mouse models showed sustained reductions in body weight and improvements in metabolic markers over extended treatment. Long-term human safety is completely unknown.
Safety notes & concerns
Full safety guide →- ⚠no published human clinical trials — all evidence is preclinical
- ⚠not FDA-approved for any indication
- ⚠technically a small molecule, not a peptide — regulatory pathway and safety profile differ
- ⚠long-term effects of NNMT inhibition in humans are completely unknown
- ⚠NAD+ and SAM are involved in hundreds of biological processes — chronic NNMT inhibition could have widespread unintended effects
- ⚠sourcing from research chemical suppliers carries significant purity and contamination risks

Frequently asked questions
Is 5-Amino-1MQ actually a peptide?
No. 5-Amino-1MQ is a small molecule quinolinium compound, not a peptide. It is widely marketed and sold alongside peptides because it targets metabolic pathways popular in the peptide community and is sold by the same suppliers. We include it because it is commonly searched for in the peptide context.
How does 5-Amino-1MQ relate to NAD+ supplements like NMN?
Both aim to increase cellular NAD+ levels but through different mechanisms. NMN provides a direct precursor for NAD+ synthesis. 5-Amino-1MQ blocks NNMT, an enzyme that degrades NAD+ precursors. In theory, they could be complementary, but combined use has not been studied in humans.
Why is NNMT a target for obesity?
NNMT is significantly overexpressed in the fat tissue of obese individuals. It depletes SAM and NAD+, which are critical for cellular energy metabolism. In mouse models, blocking NNMT reduced fat cell size, increased energy expenditure, and prevented diet-induced obesity. However, NNMT also plays roles in drug metabolism and other processes, so inhibiting it could have unintended consequences.
