Mazdutide (10 mg Vial) Dosage Protocol
Educational reference for reconstitution and weekly administration of Mazdutide (IBI362), a dual GLP-1/glucagon receptor agonist investigated in clinical trials for weight management and type 2 diabetes treatment.
Quickstart Highlights
Mazdutide (IBI362) is currently undergoing clinical development as a dual GLP-1/glucagon receptor agonist for managing body weight and type 2 diabetes. The compound merges appetite-suppressing mechanisms with energy-expenditure advantages through simultaneous activation of both receptor types. Clinical investigations have demonstrated 6–14% body weight reduction over 24–48 week periods with predominantly mild gastrointestinal side effects.
- Reconstitute: Add 3.0 mL bacteriostatic water to achieve approximately 3.33 mg/mL concentration
- Standard weekly range: 2.5–5 mg once weekly (subcutaneous)
- Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL = approximately 33.3 mcg on a U-100 insulin syringe
- Storage: Lyophilized powder: −20 °C or below; reconstituted solution: refrigerate at 2–8 °C (35.6–46.4 °F), discard after 28 days
Dosing & Reconstitution Guide
Educational resource for reconstitution procedures and weekly dosing
Standard Titration Protocol (3.0 mL = ~3.33 mg/mL)
| Timeframe | Weekly Dose | Insulin Units | Volume (mL) |
|---|---|---|---|
| Weeks 1–4 | 2.5 mg | 75 units | 0.75 mL |
| Weeks 5–8+ | 5 mg | 150 units | 1.50 mL |
Frequency: Once weekly via subcutaneous injection
Advanced/High-Dose Protocol (2.0 mL = 5.0 mg/mL)
For accelerated dosing, reconstitute with 2.0 mL to achieve 5.0 mg/mL concentration:
| Weeks | Weekly Dose | Units | Volume |
|---|---|---|---|
| 1–4 | 5 mg | 100 units | 1.00 mL |
| 5–8 | 7.5 mg | 150 units | 1.50 mL |
| 9–12+ | 10 mg | 200 units | 2.00 mL |
Caution: Doses exceeding 6 mg weekly increase gastrointestinal side effect risk and require clinical oversight. Split injections greater than 3.0 mL total volume into two separate sites.
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with sterile syringe
- Inject slowly down vial wall (avoid foaming)
- Gently swirl until dissolved—do not shake vigorously
- Label with date and refrigerate at 2–8 °C (35.6–46.4 °F) protected from light
How This Works
The dual agonist architecture activates both GLP-1 and glucagon signaling pathways simultaneously. This combination delivers glucose homeostasis regulation alongside metabolic acceleration—distinguishing it from single-target GLP-1 therapeutic agents. Phase 2 research demonstrated 6.7–11.3% body weight reduction at 3–6 mg weekly dosages over 24 week durations. Phase 3 trials have reported sustained 11–14% weight loss with 4–6 mg maintenance dosing over 48 week periods.
Potential Benefits & Side Effects
Findings from clinical trial research literature.
Reported Benefits
- 6–14% weight reduction (clinical trial range)
- Approximately 1.7% HbA1c improvement in type 2 diabetes cohorts
- Approximately 7% concurrent weight loss in diabetic populations
- Improved lipid profiles and glucose control
- Once-weekly dosing convenience
Common Adverse Effects
- Gastrointestinal: Nausea, vomiting, diarrhea, constipation (typically mild-to-moderate, diminishing over time)
- Injection site: Redness, swelling, mild discomfort
- Mitigation: Gradual titration significantly improves tolerability
Injection Technique
General subcutaneous administration guidance from clinical protocols.
- Clean vial stopper and injection site with alcohol swabs; air-dry completely
- Use aseptic technique throughout
- Pinch skinfold; insert needle at 45–90° into subcutaneous fatty tissue
- Do not aspirate for subcutaneous administration
- Inject slowly over 5–10 seconds
- Apply gentle pressure post-injection; do not rub
- Rotate sites: abdomen (2+ inches from navel), thighs, upper arms
- For volumes exceeding 3 mL, divide into two injections at separate sites
Important Notes
Practical considerations for consistency and safety protocols.
- Use new sterile insulin syringe for each weekly injection
- Rotate injection sites systematically to prevent lipoatrophy and irritation
- Allow reconstituted vial to reach room temperature before withdrawing to reduce viscosity
- Document dose, site, and side effects for protocol optimization
- This guidance is for research/educational purposes only; not medical advice
Storage Requirements
- Lyophilized: −20 °C (−4 °F) or below; protect from moisture and light
- Reconstituted: 2–8 °C (35.6–46.4 °F); use bacteriostatic water for multi-dose stability
- Critical: Never freeze reconstituted solution; avoid freeze–thaw cycles
- Discard: After 28 days or if cloudiness/particulates appear
Supply Calculation (8–16 Week Protocol)
| Duration | Vials Needed | Syringes | Bacteriostatic Water | Alcohol Swabs |

| 8 weeks | 3 vials | 8 syringes | 1 × 10 mL bottle | 16 swabs |
| 12 weeks | 5 vials | 12 syringes | 2 × 10 mL bottles | 24 swabs |
| 16 weeks | 7 vials | 16 syringes | 3 × 10 mL bottles | 32 swabs |
