Semaglutide is a GLP-1 receptor agonist used in weight management and metabolic health research. Unlike most peptides where you start at your target dose, semaglutide requires a gradual dose escalation — called titration — to minimize gastrointestinal side effects. Skipping or rushing this titration is the most common mistake users make.
Why Titration Matters
GLP-1 receptor agonists slow gastric emptying and affect appetite signaling in the brain. When introduced too quickly, the most common result is significant nausea, vomiting, and digestive discomfort. Slow titration allows the body to adapt to each dose level before increasing.
Standard Titration Schedule
This follows the clinical protocol used for the 2.4mg target dose (weight management):
| Weeks | Weekly Dose | Purpose |
|---|---|---|
| Weeks 1-4 | 0.25 mg | Introduction — body adjusts to GLP-1 activity |
| Weeks 5-8 | 0.5 mg | First increase — mild appetite suppression begins |
| Weeks 9-12 | 1.0 mg | Therapeutic range for some users |
| Weeks 13-16 | 1.7 mg | Higher therapeutic dose |
| Week 17+ | 2.4 mg | Maximum dose (not all users need this) |
Not everyone needs to reach 2.4 mg. Many users find that 1.0 mg or 1.7 mg provides sufficient appetite suppression and metabolic benefits. The right dose is the lowest effective dose — increase only if the current level is not producing adequate results.
Reconstitution for Compounded Semaglutide
Compounded semaglutide typically comes in 5mg lyophilized vials. Here is how to calculate doses at each titration level:
5mg Vial + 2mL Bacteriostatic Water
Concentration: 2,500 mcg per mL (25 mcg per syringe unit)
| Weekly Dose | MCG | Syringe Units |
|---|---|---|
| 0.25 mg | 250 | 10 units |
| 0.5 mg | 500 | 20 units |
| 1.0 mg | 1,000 | 40 units |
| 1.7 mg | 1,700 | 68 units |
| 2.4 mg | 2,400 | 96 units |
5mg Vial + 3mL Bacteriostatic Water
Concentration: 1,667 mcg per mL (16.67 mcg per syringe unit). This is more dilute, which makes the lower titration doses easier to measure precisely:
| Weekly Dose | MCG | Syringe Units |
|---|---|---|
| 0.25 mg | 250 | 15 units |
| 0.5 mg | 500 | 30 units |
| 1.0 mg | 1,000 | 60 units |
Vial Planning Across the Full Titration
Knowing how many 5mg vials you need for the complete titration prevents mid-protocol gaps:
| Phase | Weekly Dose | Weeks | Total Used |
|---|---|---|---|
| 0.25 mg | 0.25 mg | 4 | 1.0 mg |
| 0.5 mg | 0.5 mg | 4 | 2.0 mg |
| 1.0 mg | 1.0 mg | 4 | 4.0 mg |
| 1.7 mg | 1.7 mg | 4 | 6.8 mg |
| 2.4 mg | 2.4 mg | 4 | 9.6 mg |
| Full titration total | 20 weeks | 23.4 mg (5 vials) |
When to Hold a Dose Level Longer
The 4-week minimum at each dose level is a guideline, not a hard rule. Stay longer at a dose if:
- You are still experiencing nausea or digestive discomfort at the current dose
- The current dose is already producing adequate appetite suppression and weight loss
- You have a history of GI sensitivity
There is no penalty for staying at a lower dose longer. Many protocols run 6-8 weeks at each level for patients who are more sensitive.
Injection Day and Timing
Semaglutide is injected once per week, on the same day each week:
- Choose a consistent day (many pick Sunday or Monday)
- Inject subcutaneously in the abdomen, thigh, or upper arm
- Rotate injection sites within the same general area
- If you miss a dose by 1-2 days, take it as soon as you remember. If more than 5 days late, skip that dose and resume on the next scheduled day
