5-Amino-1-methylquinolinium · NNMT inhibitor · oral small molecule (not a peptide)
The compound that targets the enzyme telling your fat cells to hoard fat. Block that enzyme, and fat cells shift from storing toward burning — while cellular NAD+ climbs at the same time. It's oral, it's not a peptide, and it's routinely oversold as a GLP-1 rival. This profile sets the record straight.
Why This Page Exists
5-Amino-1MQ has a genuinely clever mechanism and a genuinely thin evidence base, and the market ignores both halves — selling it as a peptide (it isn't) and as a GLP-1 alternative (it isn't). The real story: it inhibits an enzyme called NNMT that's overexpressed in fat cells and aging tissue, which redirects fat metabolism and preserves NAD+. That's mechanistically elegant. It's also entirely preclinical in humans. Both facts belong on the same page.
Regulatory & Classification
Not FDA-approved for any use. All data is preclinical (rodent models); human dosing is extrapolated.
A ~159 Da quinolinium compound with no amino-acid chain. Sold by peptide vendors, but chemically and practically not a peptide — which changes sourcing and quality expectations.
Can be taken orally — a real convenience advantage over injectables. (Some reference protocols also list an injectable form; the two routes differ in bioavailability.)
Not explicitly prohibited as of recent lists, but metabolic-modulator categories may apply — athletes should confirm.
Mechanism of Action
NNMT (nicotinamide N-methyltransferase) is overexpressed in adipose tissue and aging cells. When overactive, it promotes fat storage and burns through nicotinamide, lowering NAD+. Inhibiting it releases both brakes at once.
5-Amino-1MQ → ↓ NNMT → fat cells shift storage → oxidation · ↑ intracellular NAD+The landmark rodent finding: NNMT inhibition reduced fat mass and improved insulin sensitivity without the animals eating less. This is metabolic redirection — the opposite of how GLP-1s work (which suppress appetite). It doesn't affect ghrelin or the central nervous system.
Rather than feeding NAD+ precursors in (like NR or NMN), it stops NNMT from consuming them. The downstream effects overlap with direct NAD+ support — energy metabolism, DNA repair, sirtuin activation — which is why it also carries a longevity angle.
Unlike GLP-1s (appetite) or AOD-9604 (direct lipolysis), 5-Amino-1MQ works at the enzymatic regulatory level of fat-cell behavior. That's why it's positioned as complementary to those compounds, not a replacement for them.
Primary Use Cases
Evidence Summary
| Basis | Type | Key finding |
|---|---|---|
| Rodent obesity models (Kraus, Neelakantan et al.) | Preclinical | NNMT inhibition reduced fat mass and improved insulin sensitivity without reduced food intake. |
| NAD+ / metabolic mechanism | Preclinical | NNMT inhibition preserves intracellular NAD+, supporting sirtuin activity and energy metabolism. |
| Community / biohacker experience | Anecdotal | Subtle fat-reduction and energy effects reported at 3–6 weeks; far milder than GLP-1s. |
| Human clinical trials | — | None. All human dosing is extrapolated from animal data. |
Protocols
Educational reference only — no human trials establish dosing, and cycling is advised to maintain NNMT responsiveness.
The dominant real-world format. Taken in the morning, fasted, ideally pre-cardio to align with fat oxidation.
A lower-exposure injectable protocol also exists; note the two routes differ substantially in bioavailability, so oral and injectable doses are not interchangeable.
Cycling preserves enzyme responsiveness; best evaluated over a full 8-week block, since effects are subtle.
