Why Is 2.5mg the Starting Dose?
The 2.5mg strength is designed as a titration dose.
It allows your digestive system to adapt gradually to:
- Slower gastric emptying
- Appetite suppression
- Hormonal changes triggered by GLP-1 and GIP activity
Starting at a low dose helps reduce nausea and other gastrointestinal side effects.

- Reduced appetite
- Feeling full sooner
- Smaller portion sizes
