i notice nothing and i have used two diff brands one was bluesky and now purchase pep.both are working at keeping me lean but i dont fell any thing at all even at 100mcg.i all ways never would use t3 or anything like that because i thought they made you fell all crack out and stuff like clen does or something.but not true for me with t3 and i can not even take pre work out stuff so if that tells you something.
I'd be careful upping the dose to quickly,t-3 will burn through muscle too.
Taking it with 900/400/400 test/tren/deca - haven't lost any weight yet, but I am visibly getting leaner. I have really cleaned up my diet, and I am hitting cardio hard 3-4 times a week, so it is difficult to tell what is doing what.
As for the T3, I think it increases my resting heart rate . . .
Shirt was soaking wet after cardio this morning, and THAT is a first.
