What Is 5-Amino-1MQ?
Published Sep 21, 2026 · 10 minute read
5-Amino-1MQ is a synthetic small molecule that blocks nicotinamide N-methyltransferase, or NNMT. Researchers study it because NNMT connects vitamin B3 metabolism, cellular NAD+ and the way fat cells use energy. Mouse experiments found weight loss and improved muscle repair, attracting interest from people pursuing fat loss without appetite suppression. Human treatment trials have not established those benefits.
Key Takeaways
- 5-Amino-1MQ is a synthetic small molecule that inhibits NNMT, an enzyme involved in nicotinamide and methyl-group metabolism. It is not a peptide.
- In an 11-day experiment with nine obese male mice per group, treated mice lost about 5.1% of starting body weight; controls gained about 1.4%.
- The same study reported about 35% less mass in one fat depot versus controls. That is different from losing 35% of total body fat.
- Muscle-repair findings come from chemically injured muscle in aged mice. They do not establish muscle retention during a human cut.
- The literature and registry searches for this guide identified no published human treatment trial or matching ClinicalTrials.gov registration. Human dose, half-life and side-effect rates remain unestablished.
The appeal during a cut is easy to understand: lose fat while keeping enough appetite to eat protein and train. The research behind that idea includes a short obesity experiment, cell-culture measurements and an aged-muscle injury model. Each answers a different question.

1. How does 5-Amino-1MQ work?
NNMT transfers a methyl group from S-adenosylmethionine, abbreviated SAM, onto nicotinamide, a form of vitamin B3. The products are 1-methylnicotinamide and S-adenosylhomocysteine. Nicotinamide can also enter the salvage pathway that recycles it into NAD+, a coenzyme involved in energy metabolism and cellular repair.
That creates two connections researchers can investigate. NNMT uses a potential NAD+ precursor, and it consumes methyl groups that cells also use elsewhere. Blocking the enzyme can change both processes. Describing NNMT as directly “breaking down NAD+” skips the actual reaction: its substrate here is nicotinamide.
In Kraus and colleagues’ 2014 Nature paper, reducing NNMT expression with antisense oligonucleotides protected mice against diet-induced obesity. Researchers linked the effect to higher energy expenditure and changes in adipose NAD+, SAM and polyamine metabolism. Polyamines are small molecules involved in cell function; making and processing them can consume metabolic fuel.
That experiment tested suppression of a gene’s expression. Researchers subsequently tested whether a small molecule could inhibit the enzyme’s activity and produce useful effects. 5-Amino-1MQ came from that drug-development work.
2. The 5-Amino-1MQ weight-loss study, in numbers
Neelakantan and colleagues’ paper appeared online in 2017 and in the January 2018 issue of Biochemical Pharmacology. Those two dates can make the same study look like two separate experiments in online summaries.
The obesity experiment included 18 male mice, nine per group, after 16 weeks on a high-fat diet. Researchers continued that diet and administered either saline or 5-Amino-1MQ by subcutaneous injection for 11 days.
| Outcome | Reported result | What was measured |
|---|---|---|
| Body weight, treated mice | About 5.1% below baseline; a 2.0 g decrease | Change within the treatment group |
| Body weight, controls | About 1.4% above baseline; a 0.6 g increase | Change within the saline group |
| Epididymal fat-pad mass | About 35% lower than controls | One dissected white-fat depot at the end of treatment |
| Fat-cell size | More than 30% lower than controls | Cross-sectional area in that depot |
| Total cholesterol | About 30% lower than controls | End-of-study plasma measurement |
| Food intake | No statistically significant group difference | Cumulative intake of 26.2 g versus 28.1 g in controls |
The fat-pad result cannot be relabeled “35% total body-fat loss.” Researchers weighed a specific depot after treatment; they did not report a 35% reduction in each mouse’s whole-body fat from baseline. Likewise, the 5.1% weight decrease and the comparison against weight-gaining controls use different denominators.
Unchanged measured food intake supports investigating an effect beyond eating less. It does not demonstrate that people can take 5-Amino-1MQ, keep their usual calorie intake and reliably lose fat. Nine mice per group over 11 days cannot establish lasting effects, weight regain after withdrawal or outcomes in lean athletes.
Why the mouse dose is easy to misquote
The methods report 20 mg/kg per injection, three times daily. They also express the daily amount as approximately 34 mg/kg of the parent compound after accounting for the salt’s mass. These are two descriptions of the same experimental exposure.
Neither value supplies a human dose. Converting milligrams by body weight would still leave absorption, metabolism, tissue exposure and toxicity unanswered. The experiment also says nothing directly about whether an oral capsule reproduces those injection results.
3. Which studies concern the compound, the target or people?
NNMT research spans genetic experiments, several drug candidates and measurements in human tissue. A paper about NNMT is not automatically a treatment study of 5-Amino-1MQ.
| Study and authors | Year / source | Design | Relevance |
|---|---|---|---|
| Nicotinamide N-methyltransferase knockdown protects against diet-induced obesity, Kraus et al. | 2014, Nature | Gene knockdown in mice and cell experiments | Supports NNMT as a metabolic target |
| Human adipose NNMT expression and insulin resistance, Kannt et al. | 2015, Diabetologia | Human tissue and blood measurements, including exercise and surgery cohorts | Connects NNMT biology to human metabolic disease |
| Selective and membrane-permeable NNMT inhibitors, Neelakantan et al. | 2018, Biochemical Pharmacology | 5-Amino-1MQ in cultured cells and obese mice | Direct preclinical evidence for this compound |
| A small molecule inhibitor of NNMT for metabolic disorders, Kannt et al. | 2018, Scientific Reports | JBSNF-000088 in mice | Evidence for a different NNMT inhibitor |
| NNMT inhibitor and aged skeletal muscle regeneration, Neelakantan et al. | 2019, Biochemical Pharmacology | 5-Amino-1MQ in aged mice with muscle injury and cultured muscle cells | Direct preclinical muscle-repair evidence |
The human study by Kannt and colleagues found approximately twice as much NNMT expression in two types of white adipose tissue in participants with type 2 diabetes compared with controls. Exercise and bariatric surgery were associated with lower adipose NNMT expression. Nobody in that study received 5-Amino-1MQ.
For this guide, searches of PubMed, Europe PMC and ClinicalTrials.gov used the short name and related chemical terminology. On September 21, 2026, the registry returned no matches for “5-amino-1MQ” or “5-amino-1-methylquinolinium”; the literature reviewed did not identify a published human treatment trial. These searches describe the public evidence found, without ruling out unpublished work or studies registered under other names.
4. NAD+, energy and longevity claims
In the original fat-cell experiments, NAD+ measurements were roughly 1.2–1.6 times those in untreated cells across the tested 1–60 micromolar concentration range. The individual comparison reached statistical significance at 10 micromolar. These were cultured mouse adipocytes, so “raises NAD+ by 60%” would need that context attached.
An increase in a cellular coenzyme does not quantify how energetic a person feels, their exercise performance or their lifespan. The studies reviewed here do not establish human improvements in fatigue, VO₂ max, biological age or survival from taking 5-Amino-1MQ.
NMN and NR enter NAD+ precursor pathways, while 5-Amino-1MQ inhibits an enzyme that uses nicotinamide. The mechanisms make combinations a research question. They do not establish that stacking these compounds raises useful tissue NAD+ more effectively or produces better health outcomes. A change in a blood marker would also need evidence connecting it to the outcome someone wants.
5. Muscle preservation, recovery and bodybuilding
The 2019 muscle paper tested 24-month-old male mice. Researchers injured the tibialis anterior, a lower-leg muscle, with barium chloride and examined recovery with NNMT inhibition. Treatment began before the injury.
Treated mice had greater muscle stem-cell activity and larger regenerating fibers. The paper reported about 70% higher peak torque in the injured muscle compared with controls. Torque measures rotational force; here it assessed recovery of muscle function after a controlled chemical injury.
That result gives researchers a reason to investigate age-related repair problems. It cannot predict a 70% strength increase in a healthy lifter. The experiment did not test hypertrophy from resistance training, soreness after a workout or preservation of lean mass while using a GLP-1 drug.
For body recomposition, the missing experiment would measure fat mass, lean mass and performance during a defined calorie deficit. A lower scale weight in obese mice and better repair in a separate injury study cannot jointly establish muscle-sparing fat loss in people.
6. Oral 5-Amino-1MQ, injections and half-life
The original paper included artificial-membrane and intestinal-cell permeability tests. Those assays help screen whether molecules can cross barriers, but cannot measure how much of a swallowed dose reaches human circulation or adipose tissue.
A separate 2018 Kannt study reported about 40% oral bioavailability in mice for JBSNF-000088. That molecule is a different NNMT inhibitor. Its absorption and roughly 0.4-hour apparent oral half-life cannot be assigned to 5-Amino-1MQ.
The evidence reviewed here does not establish a human oral or injected half-life for 5-Amino-1MQ. There is consequently no validated basis for a once-daily schedule, split dosing, a loading phase or a particular cycle length. A half-life calculator can model an assumption; it cannot supply the missing pharmacokinetic study.
7. Side effects and safety gaps
The short obesity study reported no observable adverse effects under its experimental conditions. That observation is useful for early drug development, but cannot estimate how often a person might develop an adverse effect or whether months of exposure would be tolerated.
Reliable human adverse-event rates, interaction studies and reproductive safety data were not established in the research reviewed. Lists of supposedly “common” side effects copied from sellers or forums have no controlled denominator. Absence of a dependable side-effect list leaves uncertainty about risk.
NNMT participates in both nicotinamide and methyl-group metabolism. The mechanistic research describes changes in SAM availability and histone methylation, chemical modifications involved in gene regulation. That makes the biological effects broader than one fat-loss measurement. It does not, by itself, prove benefit or harm from chronic human inhibition.
Product testing answers a separate question. A certificate of analysis may provide information about the tested sample’s identity or purity, depending on its methods. It cannot establish an effective human dose, clinical safety or the sterility of an injectable preparation unless those properties were specifically assessed.
8. 5-Amino-1MQ vs GLP-1 drugs, MOTS-c and NAD+ precursors
| Compound or category | Research focus | What the comparison can tell you |
|---|---|---|
| 5-Amino-1MQ | NNMT inhibition and cellular metabolism | Cell and mouse findings; no established human fat-loss estimate |
| Semaglutide / tirzepatide | Incretin receptors, appetite and glucose regulation | Human treatment programs provide weight-loss and tolerability data; see the individual guides |
| MOTS-c | Mitochondrial peptide signaling and metabolic stress | A separate experimental approach; its findings cannot validate an NNMT inhibitor |
| NMN and NR | NAD+ precursor supplementation | Different interventions with their own human studies and limitations |
No controlled human evidence identified here establishes added benefit or safety from combining 5-Amino-1MQ with semaglutide, tirzepatide or retatrutide. Claims about breaking a plateau, preserving muscle or preventing metabolic adaptation remain untested for those combinations.
Before-and-after photos cannot resolve that uncertainty. Changes in diet, training, other compounds, hydration and starting body fat can all affect the apparent result. A useful human trial would specify the formulation and dose, compare treatment against a control, measure body composition and collect adverse events. For a muscle-preservation claim, it would also need lean-mass and strength outcomes during weight loss.
9. 5-Amino-1MQ FAQ
What is 5-Amino-1MQ used for?
Researchers use 5-Amino-1MQ to investigate NNMT inhibition, fat metabolism and muscle regeneration. People discuss it for fat loss, NAD+ support and body recomposition, but those benefits have not been established in human treatment trials.
Is 5-Amino-1MQ a peptide?
No. 5-Amino-1MQ is 5-amino-1-methylquinolinium, a small molecule commonly studied as an iodide salt. It has no chain of amino acids, even though sellers often group it with peptides.
How much weight can you lose with 5-Amino-1MQ?
There is no established human weight-loss estimate. A short mouse study reported about 5.1% weight loss from baseline after 11 days of injections. That result cannot predict pounds lost by a person or the effects of oral capsules.
Does 5-Amino-1MQ increase NAD+?
Researchers measured increased NAD+ in cultured mouse fat cells exposed to 5-Amino-1MQ. The result supports a cellular mechanism; it does not establish increased NAD+ in human muscle, better energy or longer life after taking it.
What is the recommended 5-Amino-1MQ dosage?
No clinically validated human dose, cycle or titration schedule has been established. Mouse injection doses and doses advertised for capsules cannot supply a tested human regimen.
Does oral 5-Amino-1MQ work?
The original paper included laboratory membrane-permeability tests, but its obesity experiment used injections. This guide found no human oral study establishing absorption, fat loss or an effective capsule dose.
What are the side effects of 5-Amino-1MQ?
Reliable human side-effect frequencies and long-term safety data are unavailable. Short mouse studies reported no obvious adverse effects under their conditions; they cannot establish the safety of repeated human use.
What is the half-life of 5-Amino-1MQ?
A dependable human elimination half-life has not been established in the research reviewed here. A laboratory permeability result or a half-life from a different NNMT inhibitor cannot determine a dosing interval.
Can you stack 5-Amino-1MQ with tirzepatide or retatrutide?
The reviewed evidence does not establish the safety or added benefit of either combination. Different proposed mechanisms do not demonstrate extra fat loss, muscle preservation or a safe dose ratio.
