I am a 60-year-old male, 6’1”, started on tirzepatide in April 2024 at 237 lbs and reached 185 lbs, just short of my 179 goal. Since early 2025 I have been stuck despite lifting, walking several days a week, keeping a calorie deficit and hitting protein targets. I moved to retatrutide earlier this year and added cagri for hunger control, reaching 10 mg retatrutide weekly, yet the scale has crept back to 192-193 lbs with the extra weight at my waist. My 34 jeans are tightening and I am thinking of going back to 36s. Constipation was the main issue I had on tirzepatide.
