5-Amino-1MQ: Reference Overview and Reconstitution Notes

5-Amino-1MQ is a man-made, small chemical compound that blocks a specific enzyme. It is grouped with research compounds studied for metabolism and weight regulation. It is research-only and not approved by the FDA.

5-Amino-1MQ

What it is

Key point: 5-Amino-1MQ is a man-made compound studied in laboratory and animal models for its effects on metabolism. It has no approved human use and no published human clinical trials.

5-Amino-1MQ (full name: 5-amino-1-methylquinolinium) is a man-made chemical compound, not a peptide. It is small enough to pass through cell membranes (the thin outer walls of cells). Scientific studies describe it as a selective blocker of an enzyme called nicotinamide N-methyltransferase (NNMT). An enzyme is a protein that speeds up specific chemical reactions inside cells. It is often listed alongside research peptides for convenience only.

Research context and categorization

Mechanism of Action

5-Amino-1MQ is grouped with research compounds studied for metabolism (how cells make and use energy) and weight regulation. Researchers often discuss it in connection with two important chemical cycles in cells: NAD+ and SAM (S-adenosylmethionine). These cycles help cells produce energy and carry out many other chemical tasks.

Here is how NNMT fits in. Cells use a building block called nicotinamide to make NAD+, which helps power energy production. NNMT takes that building block and converts it into a different molecule (called 1-methylnicotinamide), using a chemical called a methyl donor. Think of it like a machine that diverts raw materials away from a factory before they can be used. Studies report that NNMT is more active in older fat tissue and in tissue under metabolic stress. Researchers study what happens when they block this enzyme.

Preclinical Research Focus

In simple terms, 5-Amino-1MQ is studied for how it affects NAD+ levels inside cells. Researchers look at it in connection with fat tissue metabolism, body composition, how cells handle glucose (sugar), and how skeletal muscle (the muscles attached to bones) ages. All of this work is done in preclinical models, meaning laboratory and animal studies.

The most often cited study is from 2018. Researchers gave the compound to mice that had gained weight from their diet. The mice showed reduced body weight and fat mass, without any change in how much they ate. These findings are strictly investigational. There are no published human clinical trials and no confirmed or approved human benefit. Everything described here comes from laboratory and animal research only, not from established human outcomes.

Status

• Regulatory status: Research-only. It is not approved by the FDA for any use. As of 2026, there is no publicly registered human trial and no IND (Investigational New Drug application, the formal request needed to begin human trials) on record. It is not a controlled substance under the U.S. Controlled Substances Act.
• Sport status: It is not listed by name on the WADA (World Anti-Doping Agency) Prohibited List. However, because it is a pharmacological substance (a drug-like compound) not approved for human therapeutic use, it may fall under S0 (Non-Approved Substances). As a metabolic modulator (a compound that affects how the body processes energy), it could also relate to S4 (Hormone and Metabolic Modulators). Athletes subject to testing should check the current status with their own governing body before assuming it is permitted.

Reconstitution notes (general)

For any lyophilized (freeze-dried) powder in a vial, working concentration is simple to calculate. Divide the milligrams (mg) of compound in the vial by the millilitres (mL) of bacteriostatic water you add. Bacteriostatic water is sterile water with a small preservative added to slow bacterial growth.

For example, 50 mg of powder mixed with 2 mL of bacteriostatic water gives a concentration of 25 mg/mL. To figure out a specific volume for your bench work, use the reconstitution calculator at peptide calculator.

Dilution and handling notes (compound-specific)

5-Amino-1MQ comes in two very different forms. Know which form you have before you mix anything.

• As an oral capsule or oral powder: This is a common format for consumer research because the compound is stable in solid form. Reconstitution does not apply here. There is nothing to mix with bacteriostatic water, and the vial-and-water steps below are not relevant. Treat it as a finished solid.
• As a lyophilized powder in a vial: Some suppliers offer it this way for reconstitution. Its reported solubility (how much can dissolve) in plain water at room temperature is roughly 10 to 15 mg/mL. Common reconstitution ranges use about 1 to 3 mL of bacteriostatic water per 50 mg vial. That gives concentrations of about 16.7 mg/mL (3 mL) up to about 50 mg/mL (1 mL). Using less water keeps the handling volume small, but pushing the concentration well above the solubility range is where problems start.

Practical Quirks for the Powder-Vial Form

• Slow dissolution: The powder does not always dissolve right away. Direct the water down the inner wall of the vial rather than straight onto the powder cake. Then let it sit, and swirl or roll the vial gently. Full dissolution can take a few minutes to considerably longer. Stubborn material may need extended resting with occasional gentle swirling.
• Clouding and precipitation: Concentrated solutions or solutions with a high pH can go cloudy or form particles. pH is a measure of how acidic or basic a liquid is. Solubility is better in slightly acidic water and drops as pH rises. Precipitation (solid particles forming in the liquid) has been reported above roughly pH 8. To avoid this, keep the concentration within the solubility range and use fresh bacteriostatic water in a neutral to slightly acidic range. If faint particles remain, pass the solution through a 0.22 micron filter (a very fine filter that removes tiny particles). Cloudiness that will not clear means the batch should not be used.
• Avoid shaking: Hard shaking causes foaming and does not help this compound dissolve. Gentle swirling is preferred.
• Color as a flag: A yellow or brown tint means the compound has broken down through oxidation (a chemical reaction with oxygen that damages the molecule). Discoloration cannot be reversed. Discard any discolored solution rather than trying to salvage it.

If your product is the oral capsule form, skip the mixing steps entirely.

Handling and storage

Refrigerate reconstituted solution at 2 to 8 degrees Celsius and keep it away from light. Wipe the stopper with an alcohol swab before each puncture, and label the vial with the date you mixed it.

Use a general guideline of four weeks (about 28 days) for refrigerated storage. Discard anything that turns cloudy, changes color, or develops floating particles. Store sealed capsules or dry powder in a cool, dry place away from light, following the supplier label.

Frequently asked questions

What is 5-Amino-1MQ and how does it work?

5-Amino-1MQ (5-amino-1-methylquinolinium) is a synthetic, cell-permeable compound that selectively inhibits NNMT, an enzyme that diverts nicotinamide away from NAD+ synthesis; it is studied in preclinical metabolism research only.

Is 5-Amino-1MQ FDA-approved or cleared for human use?

No. It is not FDA-approved for any use. As of 2026, no IND application or registered human clinical trial is on record. It is classified as research-only and is not a controlled substance under the U.S. Controlled Substances Act.

Is 5-Amino-1MQ on the WADA prohibited list?

It is not listed by name, but as an unapproved pharmacological substance it may fall under S0 (Non-Approved Substances) or S4 (Hormone and Metabolic Modulators). Athletes subject to anti-doping testing should consult a qualified professional.

What the research community gets wrong about 5-Amino-1MQ

A few ideas about 5-Amino-1MQ come up often at the bench and do not hold up. Here is what the literature and the chemistry actually show.

• It is not a peptide. 5-Amino-1MQ is a small synthetic molecule (a quinolinium salt, PubChem CID 950107), not a chain of amino acids. It gets filed next to research peptides for convenience, but peptide handling habits do not all carry over.
• Reconstitution often does not apply. Much of what is sold is an oral capsule or dry powder, which is a finished solid with nothing to mix. Only the lyophilized powder-in-a-vial form uses bacteriostatic water. Check which form is on your bench before you reach for a syringe.
• The published evidence is animal and cell work only. The most cited reports (Neelakantan et al., 2018, and a 2022 follow-up) describe results in diet-induced obese mice, not people. There are no published human trials, so results in vials say nothing about outcomes in a body.
• A more concentrated mix is not a stronger mix. Reported water solubility sits near 10 to 15 mg/mL, and clouding or particles show up as pH climbs past roughly 8. Pushing past those limits does not pack in more usable compound, it just drops solid out of solution.
• Color change in solution is a warning, not a quirk. The solid can look pale to orange, but a mixed solution that turns yellow or brown is showing oxidation (breakdown), and that cannot be reversed. Discard it rather than trying to save it.

From our bench: If you have reconstituted the powder-in-a-vial form, we want your real numbers, not a guess. Tell us the concentration you mixed (mg per mL), the pH range of the bacteriostatic water you used, and how long the cake took to fully dissolve before the solution ran clear. If you saw clouding, note the concentration and pH where it started. Send the measurement you actually recorded and we will add anonymized bench observations here.
