Mazdutide vs Adipotide
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: IBI362, LY3305677
Mazdutide is a GLP-1 and glucagon dual agonist, which puts it between semaglutide (GLP-1 only) and retatrutide (GLP-1, GIP and glucagon). It is built on oxyntomodulin, a natural gut hormone that hits both receptors, rather than on a GLP-1 backbone. It is furthest along in China, where it is approved for both weight management and type 2 diabetes. Western approval has not happened.
Also: FTPP, Fat-Targeted Proapoptotic Peptide
Adipotide is an experimental peptide built to kill fat tissue by cutting off its blood supply. One half homes in on prohibitin, a protein on the blood vessels that feed white fat, and the other half is a cell-killing sequence that triggers those vessel cells to self-destruct. It produced striking weight loss in obese mice and monkeys, but it also caused kidney damage in every primate species tested, and its only human trial was terminated after enrolling 4 people with no results ever posted.
Key Comparison Insights
- Both peptides belong to the Weight Loss category, suggesting similar primary applications.
- Mazdutide has stronger research evidence (Human Trials) compared to Adipotide (Animal Studies).
Detailed Comparison
| Attribute | Mazdutide | Adipotide |
|---|---|---|
| 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 | Two receptors, two jobs. The GLP-1 arm does the familiar work: it suppresses appetite, slows gastric emptying and improves glucose-dependent insulin release. The glucagon arm is the interesting half, because glucagon is normally thought of as the hormone that raises blood sugar. At these doses the intent is to exploit glucagon's other effects, increasing energy expenditure and pushing the liver to burn fat, while the GLP-1 arm keeps blood glucose in check and cancels out glucagon's hyperglycemic tendency. That balance is the whole design: glucagon supplies extra fat burning that GLP-1 alone cannot, and GLP-1 supplies the safety margin that makes adding glucagon viable. Reported reductions in liver fat are consistent with the glucagon component doing what it is meant to. | The molecule has two parts joined together. The targeting part, CKGGRAKDC, was found by screening peptides in living mice for ones that stick to fat-tissue blood vessels; it binds prohibitin on the endothelial cells lining white fat vasculature. The payload, D(KLAKLAK)2, is a known pro-apoptotic peptide that disrupts mitochondrial membranes once inside a cell, setting off programmed cell death. Kill the vessels and the fat tissue they supply is starved and resorbed. This is a destructive mechanism, not a metabolic nudge like GLP-1 drugs, and that matters for safety: prohibitin is not exclusive to fat vessels, and the kidney's proximal tubule cells turned out to be a clear off-target casualty in monkeys. |

| Research Summary | The pivotal trial is GLORY-1, published in the New England Journal of Medicine in 2025: 610 Chinese adults with overweight or obesity over 48 weeks. Mean weight reduction was 11.0 percent at 4 mg and 14.0 percent at 6 mg, alongside improvements in liver fat, blood pressure and lipids. A 9 mg dose has since been studied in phase 2 (about 12.8 percent at 24 weeks) and is in phase 3. Tolerability followed the pattern of the whole class, dominated by dose-dependent nausea, vomiting and diarrhea during titration. One caveat matters when reading these numbers: GLORY-1 enrolled a population with a mean BMI of 31.1, against roughly 38 in the Western trials of semaglutide and tirzepatide, so the percentages are not directly comparable to SURMOUNT-1 or STEP-1 results. There is no completed Western phase 3 program, so neither the FDA nor the EMA has assessed it, and meaningful head-to-head data against tirzepatide or retatrutide does not exist. | The concept came from Kolonin and colleagues (Nature Medicine, 2004), who reported that ablating fat vasculature reversed obesity in mice. The key primate study is Barnhart et al. (Science Translational Medicine, 2011) from MD Anderson. Obese rhesus monkeys given 0.43 mg/kg/day subcutaneously for 28 days lost 7.4% to 14.7% of body weight (average 10.6%) while controls stayed roughly flat, with MRI and DEXA confirming fat loss and clear improvements in insulin resistance. Lean monkeys at the same dose did not lose weight. The cost: serum creatinine rose in a dose-dependent way above 0.25 mg/kg, and the authors documented kidney tubule injury with glucose and protein in the urine, dehydration at higher doses, and low phosphorus and potassium. Most of it reversed within 28 days, but one treated monkey in each study still had residual changes. A first-in-human phase I trial at MD Anderson in obese men with metastatic prostate cancer (NCT01262664) started in 2012, enrolled only 4 patients, and was terminated at the investigator's request in 2019 with no results posted. That is the whole human record. Nobody knows the safe human dose, and the kidney signal is the opposite of reassuring. |
Frequently Asked Questions: Mazdutide vs Adipotide
What is the difference between Mazdutide and Adipotide?
Mazdutide is a weight loss peptide that mazdutide is a glp-1 and glucagon dual agonist, which puts it between semaglutide (glp-1 only) and retatrutide (glp-1, gip and glucagon). it is built on oxyntomodulin, a natural gut hormone that hits both receptors, rather than on a glp-1 backbone. it is furthest along in china, where it is approved for both weight management and type 2 diabetes. western approval has not happened. Adipotide is a weight loss peptide that adipotide is an experimental peptide built to kill fat tissue by cutting off its blood supply. one half homes in on prohibitin, a protein on the blood vessels that feed white fat, and the other half is a cell-killing sequence that triggers those vessel cells to self-destruct. it produced striking weight loss in obese mice and monkeys, but it also caused kidney damage in every primate species tested, and its only human trial was terminated after enrolling 4 people with no results ever posted. The main differences lie in their mechanisms of action and clinical applications.
Which is better, Mazdutide or Adipotide?
Neither is universally "better" - the choice depends on your specific goals. Mazdutide is typically used for weight loss purposes, while Adipotide is used for weight loss. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can Mazdutide and Adipotide be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using Mazdutide and Adipotide 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.
