Hi I have just done 3 months on 15 for Mounjaro and didn't lose anything. I lost 2.5 stone up until I started 15. Due to low stock I switched to Wegovey. Most pharmacies are staying that you should not start any higher than 1 when you switch but MedEx have given me the choice to switch to 2.4 or 1.7 if I want to. I have opted for 1.7 have you switched did you lose weight get side effects etc
