5-Amino-1MQ

5-amino-1-methylquinolinium · NNMT inhibitor

Not a peptide at all — a small-molecule enzyme inhibitor that blocks NNMT in fat cells, raising intracellular NAD⁺ and, in mice, converting stored fat into burned fat. No human has ever been studied on it.

00 Overview

First, a category correction. 5-Amino-1MQ is a quinolinium small molecule, not a peptide. It is stocked alongside peptides and discussed in the same protocols, but it has a different chemistry, a different route (orally active, because it crosses membranes) and a different regulatory character. A site called PrecisePep should say so on the page rather than let the shelf it sits on define what it is.

The mechanism is genuinely interesting. NNMT — nicotinamide N-methyltransferase — consumes nicotinamide and SAM to produce 1-methylnicotinamide. It is highly expressed in white adipose tissue and is upregulated in obesity. Inhibiting it does two things at once: it preserves nicotinamide for NAD⁺ salvage, raising intracellular NAD⁺, and it lifts a brake on sirtuin signalling. The reported net effect in adipocytes is a shift from a storage phenotype toward energy expenditure.[1][2]

The evidence stops at rodents. NNMT knockdown and inhibition protect against diet-induced obesity in mice, with reduced fat mass and improved insulin sensitivity — a reproducible and well-characterised finding.[1] There is no human trial of 5-Amino-1MQ. Not a small one, not a negative one, none.

Zero human data is not the same as new

The NNMT literature dates to the early 2010s. More than a decade later there is still no registered human trial of this inhibitor. Compounds with strong rodent obesity data and commercial interest usually reach humans; when they do not, the reasons are worth asking about rather than assuming the science is simply ahead of the clinic.

// Mechanism of action

NNMT inhibition. NNMT methylates nicotinamide using S-adenosylmethionine as the methyl donor. In adipose tissue this consumes nicotinamide that would otherwise re-enter the NAD⁺ salvage pathway, and it consumes SAM, the cell's universal methyl donor. Inhibiting the enzyme conserves both.

Raised intracellular NAD⁺. More nicotinamide available for salvage means more NAD⁺, which is the substrate sirtuins require. This is a fundamentally different route to raising NAD⁺ than supplying precursors such as NMN or NR — it reduces consumption rather than increasing supply, and it does so tissue-selectively where NNMT is highly expressed.

SIRT1 activation and adipocyte phenotype. Increased sirtuin activity is associated with a shift in adipocytes toward lipolysis and energy expenditure and away from storage, and with improved mitochondrial function in skeletal muscle.

Methyl-group economics. The SAM-sparing effect is the underexplored half of this mechanism. SAM is the methyl donor for DNA methylation, neurotransmitter synthesis and much else. Chronically altering its consumption in a major tissue is not obviously a small intervention, and nobody has looked at it in a human.

01 Reported benefits

Effects that have been reported. A study-tier entry means a result was published — not that the effect is established, reproducible, or transferable from a rodent to a person.

Highest confidenceReported in peer-reviewed literature, registered clinical trials, or regulatory filings. Note the model: much peptide literature is in vitro or rodent work, not human trial data.

Protection against diet-induced obesity (rodent) [1]

NNMT knockdown and pharmacological inhibition reduce fat mass and protect against diet-induced obesity in mice, with improved glucose tolerance and insulin sensitivity.

Rodent · in vivo

Increased intracellular NAD⁺ and SIRT1 activity [2]

Demonstrated in adipocyte and muscle models — the mechanistic core, and reproducible.

In vitro + rodent

Improved muscle regeneration in aged mice [3]

NNMT inhibition reported to enhance muscle stem cell function and regenerative capacity in aged animals, extending the interest beyond adipose tissue.

Rodent · in vivo

NNMT is upregulated in human obesity [4]

Human adipose tissue expression data supports the target being relevant in people, which is what makes the absence of a human trial notable rather than merely incomplete.

02 Adverse effects & risks

Adverse effects, contraindications and unknowns. The grey-market tier is where under-reporting is worst: uncontrolled use produces no systematic safety surveillance at all, so absence of a reported harm is not evidence of safety.

Highest confidenceReported in peer-reviewed literature, registered clinical trials, or regulatory filings. Note the model: much peptide literature is in vitro or rodent work, not human trial data.

No human safety data of any kind

No toxicology in humans, no pharmacokinetics, no adverse-event surveillance.

Evidence gapMost important

Well tolerated in rodent studies [1]

Animal work reports no notable toxicity at effective doses over the study durations used.

03 Dosing ranges

Figures below are documented, not recommended. Study ranges come from published protocols in the stated model; grey-market ranges are what the research community reports using and carry no safety validation of any kind.

Highest confidenceReported in peer-reviewed literature, registered clinical trials, or regulatory filings. Note the model: much peptide literature is in vitro or rodent work, not human trial data.

Rodent dosing does not convert [1]

Animal studies use milligram-per-kilogram dosing by intraperitoneal or oral route. No validated allometric conversion to a human dose exists, and none of the community figures derive from one.

Rodent · in vivo

No human dose has been established

Every figure in circulation originates from vendor suggestion and community practice.

Evidence gap
Two routes, one missing number

Oral doses cluster around 50–150 mg. Injectable doses cluster around 5–20 mg. The tenfold gap is derived entirely from the assumption that subcutaneous administration avoids first-pass metabolism — a reasonable assumption with no number attached to it, because the oral bioavailability of 5-Amino-1MQ in humans has never been measured.

If oral bioavailability is high, the injectable doses are a tenth of what people think they are taking. If it is very low, they may be considerably more. Nobody can tell you which, and the confidence with which both ranges circulate is not supported by anything.

04 Synergy & interactions

Combination effects. Almost no peptide combination has been studied as a combination in humans; stack logic is overwhelmingly mechanistic inference and community practice. Each linked compound has its own page.

Highest confidenceReported in peer-reviewed literature, registered clinical trials, or regulatory filings. Note the model: much peptide literature is in vitro or rodent work, not human trial data.

No combination studies exist

No study has combined 5-Amino-1MQ with anything.

No human protocol exists

No registered trial, no clinical protocol.

Evidence gap

05b Condition-specific interest

Every claim for 5-Amino-1MQ traces to the same body of mouse work, and the compound is sold in a format that does not match the route that work used. Both facts are worth stating before the individual claims.

No approval, no trial

There is no human data on 5-Amino-1MQ for any indication, by any route. Not a small trial, not an open-label series — none. The evidence is NNMT inhibition in cell and rodent models. It is also not a peptide; it is a small molecule.

Theorized — mouse, and the mechanism is interesting

Obesity and metabolic health

Pathophysiology
Nicotinamide N-methyltransferase is upregulated in adipose tissue in obesity, where it consumes nicotinamide and methyl groups and is proposed to slow adipocyte energy expenditure.

Mechanistic rationale
Inhibiting NNMT reduced fat mass and improved metabolic parameters in diet-induced obese mice without changing food intake, which is a genuinely interesting result and a different mechanism from anything else in this library. Mouse adipose tissue metabolism differs substantially from human, and this specific field has no human translation yet.

Community reports
Sold primarily for fat loss. Reports are confounded by everything else people change at the same time.

Components carrying the argument: NNMT inhibition — adipocyte energy expenditure

Theorized — mouse

Muscle and sarcopenia

Pathophysiology
NNMT expression rises in ageing and diseased muscle, and NAD+ availability constrains muscle stem cell function.

Mechanistic rationale
NNMT inhibition improved muscle stem cell function and regeneration in aged mice. The mechanism connects to the NAD+ story — NNMT consumes nicotinamide, so inhibiting it preserves the precursor pool. That makes it conceptually adjacent to the NAD+ field with the same translation gap.

Community reports
Used alongside training, which is doing the work.

Components carrying the argument: NNMT → nicotinamide preservation

Actionable

The route mismatch

Pathophysiology
Not a condition.

Mechanistic rationale
The animal work used oral administration. The grey market sells 50 mg vials for subcutaneous injection. Community subcutaneous doses are set at roughly a fifth to a tenth of oral doses on first-pass reasoning — an inference, not a measurement, and there is no pharmacokinetic data for the injected route in any species. The calculator carries a note on this for exactly that reason.

Community reports
Injection is increasingly the default despite the evidence being oral.

Components carrying the argument:

QuestionPosition
Human data?None, by any route
Is it a peptide?No — a small molecule
Evidence routeOral, in mice
Market routeSubcutaneous injection
Dose basisInference from oral, not measurement
Adjacent fieldNAD+ — same precursor pool, same translation gap
What actually has evidence for these conditions

For fat loss: an energy deficit that can be maintained, resistance training to protect lean mass, adequate protein, and sleep. The incretin class has the largest pharmacological effect with outcome data behind it. For muscle in ageing: progressive resistance training with 1.2–1.6 g/kg/day of protein has the best evidence of any intervention and improves function, not only mass.

06 Handling, reconstitution & storage

Physical-chemistry reference for laboratory handling of the lyophilised material. Reproduced so that stability and concentration mathematics can be studied — see the calculator for the arithmetic and the reconstitution guide for sterile technique.

Reconstitution

Supplied both as oral capsules and, increasingly, as 50 mg lyophilised vials for subcutaneous use. Reconstituted with bacteriostatic water in community practice, though as a small molecule rather than a peptide its solubility behaviour differs and few suppliers state a recommended diluent. Incomplete dissolution is reported more often than with peptides — inspect for undissolved material before drawing.

Storage

Powder or capsules: dry, cool, protected from light. As a small molecule it is considerably more stable than any peptide on this site. Reconstituted: refrigerated at 2–8 °C.

Common vial sizes

Commonly 50 mg vials for injection; also oral capsules at 50–150 mg.

Stability notes

Small-molecule stability — not subject to the aggregation and denaturation concerns that govern peptide handling. The practical issues here are dissolution and dose accuracy rather than degradation.

07 Legal & regulatory status

Regulatory status changes and differs by country. This is a summary for orientation, not legal advice — check your own jurisdiction.

Not approved anywhere, and not a peptide. 5-Amino-1MQ is an unapproved research chemical with no human clinical data. It is sometimes marketed alongside dietary supplements, which it is not — it has no supplement status, no drug approval and no established human dose.

Regulatory and trial claims re-checked against primary sources on 16 August 2026. Checked: no human data and no regulatory status by any route. Approvals, trial readouts and compounding decisions move faster than anything else on this page — a date here means someone looked, not that nothing has changed since.

Anti-doping

Athletes subject to WADA, USADA, UKAD, NCAA or military testing should assume any peptide is prohibited unless they have verified otherwise against the current WADA Prohibited List. Several classes here (growth-hormone secretagogues, TB-4 analogues, metabolic modulators) are explicitly named. Check the current list — it is republished annually.
