Preloaded Autoinjector | 5-Amino-1MQ | 3ml Pen | 50mg/ml
5-amino-1MQ iodide at 50 mg/mL in bacteriostatic water, 150 mg in a 3 mL pen
5-amino-1MQ (5-amino-1-methylquinolinium) is a small-molecule NNMT inhibitor, not a peptide. In this listing it comes ready-dissolved: a preloaded pen with a 3 mL glass cartridge of the iodide salt in bacteriostatic water at 50 mg/mL, 150 mg per pen, so nothing has to be weighed. Research on 5-amino-1MQ covers enzyme inhibition, fat cell metabolism and diet-induced obesity in mice; none of it used a pre-made solution.

What is in the pen
The cartridge holds a sterile solution of 5-amino-1-methylquinolinium iodide at 5% w/v, which is 50 mg/mL and 150 mg across 3 mL. The figure is the iodide salt, so in molar terms it is about 175 mM of the active cation, or roughly 0.52 mmol per pen. The solvent is bacteriostatic water with 0.9% benzyl alcohol. The safety data sheet classifies 5-amino-1MQ as harmful if swallowed and as a skin, eye and respiratory irritant, and benzyl alcohol as harmful if swallowed or inhaled, an eye irritant and a skin sensitiser.
Keep the pen at 2 to 8 °C in its carton, out of the light and capped between uses, and never freeze it. Discard it if the solution has frozen or looks cloudy or discoloured. The same salt is sold dry in the 5-amino-1MQ 50 mg vial, and peptide pen vs vial covers the general trade-offs between formats.
What the research covers
NNMT uses SAM to methylate nicotinamide, a precursor of NAD+, and Kraus and colleagues showed in 2014 that its expression rises in the fat and liver of obese and diabetic mice1. Knocking it down in those tissues protected mice against diet-induced obesity, and inhibiting it raised adipose SAM and NAD+1. The knockdown also increased the activity of ODC and SSAT, two enzymes that control polyamine flux1. Small-molecule inhibitors followed. Neelakantan and colleagues reported in 2018 that methylquinoliniums carrying a primary amine, the group that includes 5-amino-1MQ, crossed membranes readily in permeability assays, left related SAM-dependent methyltransferases alone, and were tested in cultured fat cells and in mice made obese on a high-fat diet2. Inside the cultured fat cells, those compounds reduced the enzyme’s product MNA, increased NAD+ and SAM and cut lipid synthesis2. A structurally different inhibitor from another group, JBSNF-000088, lowered body weight and improved glucose tolerance in obese mice but had no such effect in NNMT knockout mice3.
All of this is cell and mouse work, and none of it involved a solution stored in a pen. The references contain no human data on 5-amino-1MQ and nothing on how long it stays stable in water. The 5-amino-1MQ guide covers the literature in full.
How each lot is tested
Every lot is tested in PrymaLab’s own laboratory in Ashland, Kentucky before release: RP-HPLC for purity, LC-MS for identity, Karl Fischer titration for water, LAL for endotoxin and USP <71> for sterility. Published certificates are listed on the results page and can be checked by number and key on the verify page. The certificate covers the peptide lot used to fill the pen, not the finished solution. These are in-house results from PrymaLab Analytical, not an independent test, and the lab is not accredited to ISO 17025. The third-party testing guarantee on this page still applies: if any independent laboratory finds the wrong compound, or less than the stated purity or amount, the order is refunded and the cost of the test is reimbursed.
Frequently asked questions
What concentration does the pen hold, and on what basis?
50 mg/mL of 5-amino-1-methylquinolinium iodide, 150 mg in the 3 mL cartridge. The figure refers to the iodide salt, as on the vials, and works out to about 175 mM. Each salt unit carries one cation, so that is also the molar concentration of the active ion.
Does the certificate cover the solution?
It covers the 5-amino-1MQ lot used to fill the pen, tested in PrymaLab's own laboratory, and not the finished solution in the cartridge. Published certificates can be checked by number and key on the verify page.
How does the pen compare with the vials?
The vials hold dry salt at −20 °C and let you set the concentration when dissolving it. The pen is a fixed 50 mg/mL solution kept at 2 to 8 °C and never frozen. Neither format has been studied as such; the published work used the compound itself.
Is the pen for human use?
No. It is sold only for laboratory research, has no approval for human or veterinary use from the FDA or any other authority, and must not be given to people or animals.
