I was on t3 doing the 25,50,75,100 (upping the does every 4 days) and tapering back down until i hit 50 and just stayed there. I also did a Halodrol cycle for 6 weeks 75/75/75/75/100/100. After I was done with the Hdrol cycle I had very drastic weight loss. Like from 170 to 158 in a matter of weeks. I would have stopped the t3 except this is the closest i've come to a 6pack in my life.
My question is, will I quickly regain muscle once i'm done with the t3? I'm pretty happy with the fat loss and maybe the majority of the weight is fat because my strength is still about the same as it was at the end of my cycle.
