I just ordered some T-3 and plan to stack it with clen. I'm planning on doing 120mcg/day of clen, but I"m not sure on the T-3. I've seen 60mcg posted, but is that too much to screw with my thyroid? Also, what's a good length of time to run t-3? I've seen 6 weeks on that, but I just want to double check.
