Running something similar, though my Tirz is higher and Reta lower.
12mg every six days on Tirz, 4mg every six days on Reta, 2mg every six days on Cagri. Landed on this combo after a rough bout of ear ringing and skin sensitivity hit when I bumped Tirz from 7.5 to 10 a few months back.
Since then I've climbed the tirz to 10, then most recently 12. Hit a stall I can't break through. Only three weeks into this newest combo, so still early to judge results. Just 7lbs from my target.
Began with a BMI of 40.0, aiming for something in the high 20s. Under 30 puts you in overweight territory instead of obese, that's my current goal, my third one so far. The first two targets came easily just running Tirz solo, I really underestimated how well this would work!
Down 55lbs total since starting Tirz seven months back.
