How much do I take?
100 mg per day (oral, community-reported) · once daily
Best time to take
Community users typically take it in the morning; no human study has tested timing.
With food?
Can be taken with or without food (community practice); no peer-reviewed guidance exists.
If stacking
Some community users stack it with NAD+ precursors like NMN or NR because 5-Amino-1MQ raises NAD+ by a different route [1]. This combination has never been tested together in humans.
＋ Increase if
- +A lower dose is well tolerated with no side effects after several weeks (community practice, not clinically validated)
－ Decrease if
- −You notice any nausea, headache, flushing, or unusual fatigue
- −You take any medication affected by MAO-A [2]
✓ Signs of right dose
- ✓No validated markers exist in humans; in animals the signs were gradual fat and weight loss without reduced appetite [1]

Best for fat loss (research context) & metabolic health support
Best for
Fat loss research
The clearest, most repeated finding: obese mice lost body weight and fat mass on 5-Amino-1MQ without eating less [1][2]. This is the main reason people are interested — though it is animal data, not human proof.
Metabolic health support
In mice, it improved blood sugar, insulin, and liver fat [2]. Researchers see NNMT inhibition as a promising angle for metabolic syndrome [4].
NAD+ and cellular energy science
By blocking NNMT, it raises NAD+ and SAM inside cells, which supports how cells make and use energy [1][4]. This makes it interesting to people studying aging and metabolism.

04 · Administration
How do I use it?
Subcutaneous injection · Oral capsule
Reconstitution — what you need
Example
5-Amino-1MQ is most often supplied as oral capsules, which need no reconstitution. If you have a lyophilized (freeze-dried) powder for injection, a typical approach is to add 2 mL of bacteriostatic water to a vial containing 50 mg, giving 25 mg per mL. Note: injectable dosing for this compound has no human study behind it.
With 25 mg/mL solution, a 50 mg dose would be 2 mL. Because no human dose is established, any injectable use is experimental. Capsule users simply take the labeled capsule strength.
Route
Oral capsule is the most common community route; subcutaneous injection was used in animal studies [1][2]
Best sites
Technique
- 01Most community users take capsules by mouth with water
- 02If injecting, pinch the skin and insert at a 45-90 degree angle into the fat layer
- 03Rotate sites to avoid irritation
- 04No injection technique has been validated for humans with this compound
Storage · before reconstitution
Store capsules or sealed powder in a cool, dry place away from light. Refrigeration is recommended for powder to preserve stability.
Storage · after reconstitution
If reconstituted for injection, keep refrigerated at 2-8 degrees C and use within a few weeks. Do not freeze the solution.

05 · Safety
Is it safe?
2 common side effects · 2 serious
Here is the honest picture: no one has run a human safety trial on 5-Amino-1MQ. Everything we know about safety comes from mice. In those studies, the animals tolerated it well — no obvious harm, no change in appetite, and healthier livers at the doses tested [1][2]. But mice are not people, and short animal studies cannot rule out problems that show up over months or years in humans. Treat this as an experimental compound. If you are considering it, talk to a doctor first, especially if you take any medication.
All safety information is preclinical (animal and lab data). The main studies used 20 mg/kg three times daily for 11 days [1] and 10-32 mg/kg once daily for about a month [2] in mice — these are animal doses, not human doses. Lab screening found the compound can inhibit monoamine oxidase-A (MAO-A) at higher concentrations, which is why caution with MAO-sensitive drugs and foods is reasonable [2]. Human pharmacokinetics, long-term safety, and effective human doses are all unknown.

- ×Persistent nausea, headache, or fatigue
- ×You start a medication affected by MAO-A
- ×You become pregnant or are breastfeeding
This is an experimental research compound with no human safety data. This information is educational and not medical advice. Talk to a qualified healthcare provider before using it and before stopping any prescribed medication.
With other peptides
- ✓NAD+ precursors (NMN, NR) — Community users sometimes stack these to support NAD+; the combination has never been tested in humans [1]
With medications
- !MAO inhibitors — Avoid. The compound inhibited monoamine oxidase-A in lab screening, so combining could compound MAO-blocking effects [2]
- !SSRIs / serotonergic drugs — Use caution due to theoretical off-target MAO-A activity [2]
- !Drugs metabolized via MAO pathways — Discuss with a doctor before combining
With supplements
- ✓NMN or NR — Community-reported pairing to support NAD+; unstudied together in humans
- ✓Tyramine-rich foods/supplements — Theoretical caution alongside possible MAO-A inhibition [2]

How it works
Imagine your fat cells have a drain that slowly lets out the fuel they need to burn energy. That drain is an enzyme called NNMT. 5-Amino-1MQ plugs the drain. With the drain plugged, the cell keeps more fuel (NAD+) and burns fat instead of storing it [1]. In mice, this led to less body fat and smaller fat cells [1].
NNMT (nicotinamide N-methyltransferase) transfers a methyl group from SAM (S-adenosylmethionine) onto nicotinamide, producing 1-methylnicotinamide (1-MNA) and SAH (S-adenosylhomocysteine). This single reaction pulls from two systems at once: it consumes nicotinamide, a building block your cells recycle into NAD+ through the salvage pathway, and it burns through SAM, the cell's main methyl-group currency [4]. When NNMT runs fast in fat tissue, NAD+ and SAM stay low and energy expenditure drops. 5-Amino-1MQ is a nicotinamide look-alike that competitively binds NNMT's active site, so the enzyme cannot process its normal target [4]. In cultured fat cells this lowered 1-MNA and raised both NAD+ and SAM, which suppressed the building of new fat [1]. Importantly, the methylquinolinium scaffold is highly selective — it does not block related SAM-dependent methyltransferases or the NAD+ salvage enzymes — and it crosses cell membranes well, which is unusual for this class [1]. One caveat from later work: at higher lab concentrations the compound also inhibited monoamine oxidase-A, an off-target effect worth watching [2].

Not seeing results? Common reasons
- •Expecting fast results — animal changes were gradual over weeks [1]
- •No human dose is established, so a chosen dose may simply be too low or ineffective
- •Diet and activity not held steady, making any effect impossible to judge
- •Product quality varies widely for research compounds; purity is not guaranteed
- •The compound may simply not work the same way in humans as in mice

07 · Questions
Frequently asked
Is 5-Amino-1MQ actually a peptide?+
No. Despite being sold alongside peptides, 5-Amino-1MQ is a small chemical molecule (a methylquinolinium compound), not a peptide made of amino acids. It works by blocking an enzyme called NNMT [4].
Has 5-Amino-1MQ been tested in humans?+
No. Every published study is in mice or lab dishes [1][2][3]. There are no human clinical trials, so its effects and safety in people are unknown.
How does it help with fat loss?+
In fat cells, an enzyme called NNMT wastes molecules (NAD+ and SAM) your cells use to burn energy. 5-Amino-1MQ blocks NNMT, so cells keep more of that fuel and lean toward burning fat instead of storing it. In obese mice this led to less body fat without the animals eating less [1].
What dose do people use?+
There is no proven human dose. Community protocols commonly cite 50-150 mg per day by mouth, but that is not backed by any human study. Animal studies used 10-32 mg/kg by injection, which does not convert directly to a human pill dose [1][2].
Are there any safety concerns?+
The biggest concern is simply that human safety is unknown. Lab screening also found it can block monoamine oxidase-A (MAO-A) at higher concentrations, so it should not be combined with MAO inhibitors and should be used cautiously with serotonergic drugs or tyramine-rich foods [2]. Talk to a doctor first.
