I tried clen before, but I think it was bunk. I didn't feel any different even on 120mcg/day. I thought about doing t3 during a cutting cycle, but the more research I did the more risky the whole thing seemed to me. Messing with the thyroid can be dangerous. Many people have had to go on permanent thyroid replacement therapy after just one cycle of thyroid hormone. This is some of the stuff I've read on other threads and whatnot, so I'd love to hear what you guys think of this phenomenon. Apparently, the thyroid gland doesn't bounce back as surely or as readily as the HPTA. Agree? Disagree?
