5-Amino-1MQ vs Petrelintide
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: 5-amino-1-methylquinolinium, NNMT Inhibitor
First, a correction worth making loudly: 5-amino-1MQ is not a peptide. It is a small molecule (5-amino-1-methylquinolinium), and it gets lumped in with research peptides mostly because of the crowd that sells it. It blocks an enzyme called NNMT, and in obese mice it produced weight and fat loss without the animals eating less. No human trials have been published.
Also: ZP8396
Petrelintide is a long-acting amylin analog from Zealand Pharma, co-developed with Roche, designed as a once-weekly injection for obesity. The pitch is gentler weight loss than GLP-1 drugs but with far less nausea and vomiting. Two phase 2 trials read out positively in 2026 (up to 10.7% weight loss at 42 weeks), and a roughly 7,000-person phase 3 program has started. It is not approved anywhere.
Key Comparison Insights
- Both peptides belong to the Weight Loss category, suggesting similar primary applications.
- Petrelintide has stronger research evidence (Human Trials) compared to 5-Amino-1MQ (Animal Studies).

| Category | Weight Loss | Weight Loss |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | NNMT (nicotinamide N-methyltransferase) takes nicotinamide and tags it with a methyl group borrowed from SAM, the cell's main methyl donor, producing 1-methylnicotinamide. In fat tissue, high NNMT activity is thought to drain both NAD+ precursors and SAM, nudging cells toward storing fat. The hypothesis behind 5-amino-1MQ is straightforward: inhibit NNMT, and you preserve NAD+ and SAM inside adipocytes, which shifts them away from fat storage and toward burning energy. The published mouse work showed NNMT inhibition raising intracellular NAD+ and SAM, consistent with that idea. It is a plausible, well-reasoned mechanism, but in humans it remains a hypothesis, not a demonstrated effect. | Amylin is a hormone your pancreas releases alongside insulin after meals. It acts on the brainstem to make you feel full sooner, slows stomach emptying, and curbs glucagon after eating. Zealand says amylin signaling also helps restore sensitivity to leptin, the body's long-term fullness signal. Native amylin is unusable as a drug because it clumps into fibrils and lasts minutes, so petrelintide was engineered to stay stable at neutral pH, avoid fibril formation, and last a week. That stability also means it can be co-formulated with other peptides, which is why Roche plans to combine it with its own GLP-1/GIP drug. The theory is that amylin gives more of a natural fullness feeling than GLP-1 drugs do, with fewer GI side effects; the tolerability part looks real so far, the bigger-picture claims still need phase 3. |

| Research Summary | The headline study (Neelakantan et al.) tested small-molecule NNMT inhibitors in diet-induced obese mice. Treated animals lost weight (roughly 5% from baseline over about 11 days in that work) and shed white adipose mass, with reduced circulating cholesterol and no change in food intake, which points to a metabolic effect rather than appetite suppression. That is genuinely interesting preclinical data. But here is the honest part: the entire evidence base is animal and cell studies. There are no published human clinical trials demonstrating that 5-amino-1MQ causes fat loss, raises energy expenditure, or is safe over time in people. Claims of specific human fat-loss percentages from vendors are not backed by trial data. Treat it as an early-stage research compound, not a proven product. | A 16-week phase 1b trial (48 people) reported up to 8.6% mean weight loss at the highest dose versus 1.7% on placebo, with no early plateau. The phase 2 ZUPREME-1 trial (493 people with obesity or overweight, mean BMI 37) reported in March 2026 up to 10.7% mean weight loss at 42 weeks versus 1.7% on placebo. That is clearly less than semaglutide or tirzepatide produce, but tolerability stood out: no vomiting at the maximally effective dose, and side-effect dropouts (4.8%) no higher than placebo (4.9%). ZUPREME-2 (220 people with obesity and type 2 diabetes) reported in October 2026: 7.4-9.2% weight loss at 28 weeks versus 2.0% on placebo, placebo-adjusted HbA1c drops of 0.61-0.88 points, and GI dropouts of 1.9% versus 1.7%. Roche and Zealand have started phase 3a (ZUPREME-3, -4 and -5, about 7,000 people in total, including a cardiovascular-disease population). Honest take: a well-tolerated, moderate-strength drug whose real value may be as a combination partner, and the full peer-reviewed phase 2 data are still pending. |
Frequently Asked Questions: 5-Amino-1MQ vs Petrelintide
What is the difference between 5-Amino-1MQ and Petrelintide?
5-Amino-1MQ is a weight loss peptide that first, a correction worth making loudly: 5-amino-1mq is not a peptide. it is a small molecule (5-amino-1-methylquinolinium), and it gets lumped in with research peptides mostly because of the crowd that sells it. it blocks an enzyme called nnmt, and in obese mice it produced weight and fat loss without the animals eating less. no human trials have been published. Petrelintide is a weight loss peptide that petrelintide is a long-acting amylin analog from zealand pharma, co-developed with roche, designed as a once-weekly injection for obesity. the pitch is gentler weight loss than glp-1 drugs but with far less nausea and vomiting. two phase 2 trials read out positively in 2026 (up to 10.7% weight loss at 42 weeks), and a roughly 7,000-person phase 3 program has started. it is not approved anywhere. The main differences lie in their mechanisms of action and clinical applications.
Which is better, 5-Amino-1MQ or Petrelintide?
Neither is universally "better" - the choice depends on your specific goals. 5-Amino-1MQ is typically used for weight loss purposes, while Petrelintide is used for weight loss. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can 5-Amino-1MQ and Petrelintide be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using 5-Amino-1MQ and Petrelintide together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
