5-Amino-1MQ: The Fat Loss Peptide Bodybuilders Are Just Starting to Take Seriously

If you’ve been around the enhanced bodybuilding world long enough, you’ve probably heard whispers about 5-Amino-1MQ. It’s not quite mainstream yet—most lifters are still stuck on semaglutide or clenbuterol—but those who’ve experimented with this molecule are calling it the cleanest, most effortless cutting compound they’ve touched in years.

Unlike harsh stimulants or appetite-slamming GLP-1 drugs, 5-Amino-1MQ works through an entirely different mechanism—boosting NAD⁺ levels and switching on fat-burning at the cellular level. And the craziest part? It was originally studied for improving insulin sensitivity and muscle energy metabolism in aging mice.

But now it’s finding its way into stacks for recomp, mini cuts, and even aggressive fat-loss protocols among elite natural and enhanced lifters.

This guide breaks down everything we know so far about 5-Amino-1MQ: what it is, how it works, real-world results, dosing strategies, side effects, and how it stacks up against other fat loss peptides.

🧬 What Is 5-Amino-1MQ?

5-Amino-1MQ, or 5-Amino-1-methylquinoline, is a small molecule peptide derivative that works by inhibiting NNMT (nicotinamide N-methyltransferase)—an enzyme involved in energy regulation, adipogenesis (fat storage), and metabolic rate. Technically It is classified as a derivative of methylquinolinium, not a peptide

To simplify that:

5-Amino-1MQ blocks an enzyme that slows down your body’s fat-burning potential. Once that brake is removed, fat loss speeds up without touching muscle tissue or tanking your appetite.

This makes it mechanistically very different from fat burners like clenbuterol (which hits beta-adrenergic receptors) or semaglutide (which suppresses hunger by acting on GLP-1). Instead, 5-Amino-1MQ enhances metabolic flexibility and cellular energy efficiency, making your body burn more fat for fuel—even at rest.

🧪 History and Development

5-Amino-1MQ was developed as part of longevity and diabetes-related metabolic research, not as a fat burner per se. A 2018 study published in Biochemical Pharmacology showed that inhibiting NNMT led to reduced fat mass and improved insulin sensitivity in obese mice—without altering food intake.

The key result: the mice didn’t eat less, but they lost weight anyway.

That immediately caught the attention of researchers looking for non-stimulant ways to support body recomposition. Within a few years, 5-Amino-1MQ was being sold by a small number of research chemical vendors and was adopted in early biohacking and bodybuilding circles.

By 2022–2023, it became a niche peptide among enhanced lifters looking for lean bulk or recomp solutions that didn’t interfere with appetite, training, or sleep. In 2025, it’s now sitting quietly behind more popular peptides—but those who’ve used it are pushing for it to go mainstream.

⚙️ How 5-Amino-1MQ Works (Mechanism)

Let’s simplify the cellular biology:

• NNMT is an enzyme that plays a role in regulating adipose (fat) cell metabolism.

• High NNMT activity is linked with obesity, insulin resistance, and sluggish fat oxidation.

• 5-Amino-1MQ inhibits NNMT, which in turn:

  • Increases NAD⁺ availability in cells

  • Enhances mitochondrial function

  • Improves glucose metabolism

  • Encourages white fat to brown fat conversion (i.e., fat that burns more energy)

In other words, it helps your body switch from fat-storing mode to fat-burning mode, without revving up your CNS or crashing your hormones.

🕒 Half-Life and Pharmacokinetics

• Estimated half-life: ~8–12 hours

• Onset of action: Within the first week for most users

• Duration of effects: Daily dosing provides a steady, mild metabolic increase; effects may accumulate over several weeks.

Due to the relatively short half-life, most protocols involve daily or twice-daily dosing. It is water-soluble and often compounded as an injectable, though oral capsules are also available through some vendors.

💉 Recommended Dosage & Administration

While clinical dosing data is limited (this is still a research peptide), anecdotal user protocols have emerged from the bodybuilding and peptide optimization communities.

✅ Common Dosing Range:

• Oral: 50–150 mg per day

• Injectable (SC or IM): 10–20 mg daily (divided doses)

📆 Cycle Length:

• Typical cycles run 30–60 days

• Some users report stacking it during the final 4–6 weeks of a cut

• Low-dose maintenance (e.g., 50 mg oral) has been used during lean bulks for recomp effects

Note: Many users find that fat loss becomes visible within 10–14 days of consistent dosing, especially when paired with a moderate calorie deficit and resistance training.

🧍‍♂️ Real-World Fat Loss Results (User Experiences)

Here’s where 5-Amino-1MQ gets interesting. While clinical trials in humans are still sparse, a number of bodybuilders, contest preppers, and TRT patients have shared compelling results.

🔹 Case 1: Lean Recomp While Eating Maintenance

A 38-year-old lifter on TRT + MK-677 added 10 mg/day of 5-Amino-1MQ (injectable).

• After 4 weeks: down 5.2 lbs with no change to macros or training.

• Bioimpedance scan showed 1.1 lb lean mass gain, 6.3 lb fat loss.

• “It felt like cardio was more effective, even though I did less.”

🔹 Case 2: Cutting Phase Stack

A natural competitor in prep used oral 5-Amino-1MQ at 150 mg/day alongside CJC/Ipamorelin and carnitine.

• 6-week transformation: -11 lbs with zero appetite suppression, no stimulant crash.

• “It felt clean, like I was burning fat without dying.”

🔹 Case 3: Fat Loss Stalled, Rebooted with 1MQ

A 260-lb enhanced lifter hit a fat loss plateau. He added 20 mg/day (IM) of 1MQ.

• After 2 weeks, scale started moving again without lowering carbs.

• “Didn’t feel stimmed up. Just saw the scale drop and less bloating.”

⚠️ Side Effects and Safety Considerations

So far, 5-Amino-1MQ has shown a mild and clean profile, but it’s still experimental. Here’s what’s reported:

5-Amino-1MQ does not appear to affect testosterone, cortisol, or thyroid function, and does not cause appetite suppression like GLP-1s. No users report sleep disruption or stim-like crashes, making it ideal for night dosing if needed.

Still—test your sources, start low, and always monitor biofeedback.

⚖️ How 5-Amino-1MQ Compares to Other Fat Loss Peptides

Let’s rate it against some of the most commonly used peptides for fat loss.

Verdict: 5-Amino-1MQ offers one of the best balances of fat loss + safety + non-stim impact. It’s not the most powerful fat shredder, but it’s arguably the easiest to live with day to day, especially for performance athletes.

---

🔥 Ideal Use Scenarios for 5-Amino-1MQ

• Mini cuts without losing strength or crashing

• Contest prep phases where hunger is already brutal and GLP-1s aren’t an option

• Recomp phases during lean bulks

• Post-cycle recovery to stay lean while resetting hormones

• Fat loss plateaus when stims have stopped working

---

🧠 Pro Tips From Coaches & Users

• Pair it with CJC/Ipamorelin for a GH + NAD⁺ synergy

• Stack with injectable carnitine before cardio for better fat oxidation

• Use during reverse diets to offset fat regain

• Take orally with fats if using capsules—absorption improves with meals

• Avoid stacking with clen or yohimbine initially—wait to assess tolerance

💬 Final Word

5-Amino-1MQ isn’t flashy. It won’t strip off 20 lbs overnight or slam your appetite shut. But for the experienced lifter looking for a clean, low-side-effect fat burner that doesn’t interfere with sleep, hunger, or hormones—it’s a quiet winner.

Whether you’re deep in a prep, chasing body recomp, or just want to fine-tune your look without losing your edge, 5-Amino-1MQ is a tool worth trying.

Just don’t expect to find it on a GNC shelf anytime soon.
