I can pretty much start clen from 60mcg.
I can go up to 160mcg by the start of the 2nd week and not feel a thing.
The only time I feel anything is the first 3 days, the cramps, shakes, the works.
But on the 4th day, it's like I can jump to 120mcg of clen and not feel a thing.
When I first took clen, I actually felt my body heating up on the inside, now I never feel a thing, this is my 3rd cycle.
I ordered my clen from RUI, 2 bottles during the black friday sale.
I do about 2 weeks on, 3-4 weeks off.
