The research compound serious buyers are talking about — and what the science actually says.

The peptide and research compound space moves fast. In 2026, one molecule keeps appearing in the same conversations as BPC-157, NAD+ precursors, and GLP-1 research: 5-Amino-1MQ.
It is not a peptide. It is not a stimulant. It is a small-molecule NNMT inhibitor — and if you understand what that means, you already know why it matters.
What Is NNMT? A Foundational Explainer
Nicotinamide N-methyltransferase (NNMT) is an enzyme encoded by the NNMT gene and expressed primarily in adipose (fat) tissue, liver, and skeletal muscle. Its primary biochemical role is to catalyse the methylation of nicotinamide (a form of vitamin B3) using S-adenosylmethionine (SAM) as the methyl donor — producing 1-methylnicotinamide (MNA) and S-adenosylhomocysteine (SAH) as byproducts [1].
Why does this matter? Two reasons:
- NAD+ depletion: NNMT consumes nicotinamide — a direct precursor to NAD+. Elevated NNMT activity therefore reduces the pool of nicotinamide available for NAD+ biosynthesis, lowering cellular NAD+ levels [1].
- SAM depletion: NNMT uses SAM as a methyl donor. SAM is the body's universal methyl donor — required for DNA methylation, gene expression regulation, and dozens of metabolic reactions. High NNMT activity depletes SAM, disrupting the broader methylation cycle [1].
Elevated NNMT expression has been observed in adipose tissue of individuals with obesity and metabolic dysfunction in multiple studies [1, 2]. Inhibiting NNMT is therefore an active area of metabolic research — with the goal of restoring NAD+ and SAM availability at the cellular level.
What Does 5-Amino-1MQ Actually Do?
5-Amino-1MQ (5-amino-1-methylquinolinium) is a selective, cell-permeable small-molecule NNMT inhibitor. It was identified and characterised in research by Neelakantan et al. (2018) as a potent inhibitor of NNMT with favourable selectivity and cell permeability [3].
Unlike broad-spectrum metabolic compounds, 5-Amino-1MQ targets NNMT specifically — crossing the cell membrane to act at the enzymatic level. In preclinical research, NNMT inhibition with compounds in this class has been associated with:
- Restoration of NAD+ and SAM availability in adipose tissue [1]
- Influence on energy substrate utilisation and mitochondrial function [3]
- Modulation of adipogenesis-related gene expression in cell models [2]
Important context: The majority of published research on 5-Amino-1MQ is preclinical (cell and animal models). Human clinical trial data is limited. This compound is supplied for research purposes only.
This is not a fat burner. It does not suppress appetite. It works upstream — at the enzyme.
How Does It Compare to Other Research Compounds?
In 2026, the most-searched research compounds in the UK include BPC-157, TB-500, semaglutide analogues, NAD+ precursors (NMN, NR), and NNMT inhibitors like 5-Amino-1MQ. What separates 5-Amino-1MQ from the peptide category is its oral bioavailability — no reconstitution, no injection, no cold storage. One capsule. Done.

The Sourcing Problem — and Why It Matters
The research compound market has a quality problem. Underdosed capsules, unlabelled fillers, overseas shipping delays, and grey-market suppliers with no accountability. It is a real issue that compromises research integrity.
At True Ability Labs, we supply one compound. We dose it accurately. We test it. What is on the label is what is in the capsule — 50mg of 5-Amino-1MQ, nothing else. Before you buy, read our NNMT Inhibitor Buyer's Guide to know exactly what to look for.
