Maybe I have some low-octane Cagrilintide?
I had lost about 40 lbs on Tirz; starting at 3mg/6D and ramping up to 10mg/6D over a 4 month period.
4 months into this, I stalled. Gave it 4 weeks, then I added Cag at 500mcg/6D, stacked with the Tirz 10mg/6D and Reta 1mg/6D. Each staggered 2 days.
Minimal improvement after 8 weeks. Maybe down 3 or 4 lb. Raised the Cag to 1mg/6D, Reta to 2mg/6D. That netted a 7lb weight loss, then another stall.
After 4 more weeks, raised Tirz to 12/6D, Cag to 2mg/6D, Reta to 4mg/6D. Just beginning to see movement again at the end of week 1 at this dose.
Almost 8 mo's later, I'm about 10lbs from goal weight which is <30 BMI. I was exactly 40.0 BMI when I first began this Tirz adventure. Cagrilintide does appear to be a tool, but I haven't found it to be the end-all-be-all others have claimed.
