Overview
Mazdutide is an advanced next-generation dual GLP-1 and Glucagon receptor co-agonist engineered for aggressive obesity reduction and metabolic disease management.
What problem it targets: It targets severe obesity, non-alcoholic fatty liver disease (MASLD/MASH), metabolic syndrome, and stubbornly stalled weight loss on single-agent GLP-1s.
What It Does
• Powerful dual-action metabolic control: Engages GLP-1 receptors to curb appetite and slow digestion while simultaneously activating glucagon receptors to dramatically boost metabolic energy expenditure.
• Clears liver fat and enhances hepatic lipid burning: Glucagon receptor activation directly stimulates hepatic fatty acid oxidation, rapidly reversing fatty liver infiltration.
• Preserves higher caloric burn: Unlike typical dieting which slows resting metabolic rate, the glucagon component keeps energy expenditure elevated even as body weight falls.
• Realistic expectations: Injected once weekly. Clinical trials demonstrate superior weight loss and hepatic fat reduction compared to standard single-mechanism GLP-1 drugs.
Reconstitution
| Vial size | BAC water / Solvent | Concentration |
|---|---|---|
| 10 mg | + 2 mL | 5 mg/mL |
Protocol
| Phase (4 wks each) | Frequency | Dose | Units (5 mg/mL) | Notes |
|---|---|---|---|---|
| Weeks 1–4 | Once weekly | 1.5 mg | 30u | Start here; smoother GI profile than survodutide. |
| Weeks 5–8 | Once weekly | 3 mg | 60u | |
| Weeks 9–12 | Once weekly | 4.5 mg | 90u | |
| Week 13+ | Once weekly | 6 mg | 120u | Maintenance. Many cap at 4–6 mg, especially if stacked. Cycle: 4-step titration over ~12–16 weeks to 6 mg/week maintenance; each step lasts 4 weeks. Timing: same day each week, any time. Note: still raises heart rate via glucagon agonism, monitor. Women: Women lose more than men at the same dose but report more GI (start lower). In PCOS they improve cycles, lower free testosterone and raise ovulation; a real unplanned-pregnancy risk. Stop before conceiving. Men: In men, excess fat lowers testosterone; GLP-1 raises total testosterone, SHBG and gonadotropins as weight drops, and improves sperm and erectile function; and preserves fertility, unlike TRT (which suppresses sperm). |
Handling & Stacking
- Freeze-dried: -4°F.
- Reconstituted: 36–46°F.
- Best used within ~3–4 weeks, kept cold (structure-based estimate, no published data); that is close to the 28- day sterility limit, so use whichever comes first.
- Appetite suppression plus a metabolic-rate effect; steady weight loss over months.
- Investigational outside its approval region.
- Supply math 10mg → 6 vials (16-wk titration to 6 mg/wk)
Safety & Patient Education
- Fasting glucose / HbA1c (baseline + periodic) Liver enzymes; lipase if pancreatitis suspected Resting heart rate / blood pressure Renal function with significant GI losses Out of range?
- Rising glucose/HbA1c = blood sugar creeping toward diabetes (recheck, tighten diet); a falling eGFR = kidney strain, usually dehydration (hydrate, hold the dose).
