| Outcome | Grade | Effect size | Human studies | Where the evidence comes from |
|---|---|---|---|---|
| Fat loss / metabolic health | DNo human evidence | Not measurable | 0 controlled | Inhibiting NNMT with 5-amino-1MQ reduced fat mass and improved metabolic measures in mouse models of diet-induced obesity. No human trial has tested it for weight or metabolism. |
| Safety in humansadverse | DNo human evidence | Not measurable | None | No human dosing study exists; there is no safety dataset. NNMT sits at a hub of NAD+ and methylation metabolism, so systemic inhibition has plausible but unstudied off-target effects. |

What it is
5-Amino-1MQ (5-amino-1-methylquinolinium) is a small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme over-active in obese fat tissue and in some cancers. It is not a peptide, but is sold and injected in the same market.
Its reputation as a fat-loss compound comes entirely from rodent studies of NNMT inhibition.
How it is thought to work
By blocking NNMT it is thought to shift cellular NAD+ and methylation balance in fat tissue toward greater energy expenditure — shown in mice. Whether that produces safe, useful fat loss in a person is untested.
What is still unknown
- Whether it does anything to weight or metabolism in people.
- The safety of inhibiting a central metabolic enzyme systemically in humans.
- Dose, route and pharmacology in people — none established.

Regulatory status
No marketing authorisation in any member state. Supplying it for human use is an offence under national medicines law; a 'research use only' label does not change that.
Not an approved drug and not a dietary-supplement ingredient. Sold as a 'research chemical' outside the medical system; the FDA has warned against several compounds in this class.
Not licensed by the MHRA. Selling or supplying it for human use is an offence under the Human Medicines Regulations 2012.
Not on the ARTG. Supply without a prescription is unlawful; imports are seized.
No Drug Identification Number; selling it for human use is illegal.
As a non-approved substance, 5-amino-1MQ falls under WADA class S0 (non-approved substances) and is prohibited in and out of competition.
