39 years old. Metabolism has slowed down a lot. I’ve managed to put on a surprising 18 lbs over the past couple years. Even though I’m training hard and I’m eating pretty good. I’m currently 185 lbs and I’m 5’6”. how much tirzepatide should I use? I’m thinking of 2mgs a week for 12 weeks then increasing the dose to 4mgs after that. What are your thoughts?
