I've used it, I know other folks here have - it's effective.
BUT, I would like to side-step AG for a second. It seems to me that people expect WAY too much results from CLEN + T3 cycles. Let me put it this way, CLEN+T3 will help you (AT MAXIMUM) with about a 7-10% metabolic increase from BMR, what does that mean? you ask.
Well, an average 200lbs. male has an AMR of weight x 15, which = 3000 calories per day. Your BMR (basal metabolic rate) is about weight x 12 = 2400, take 7% from that's only 168calories per day. For most that will even be less, around 100calories.
Thus, you can see that T3+clen or even clen or T3 alone are NOT magic. They will help a little, but 70% of what you look like will be your DIET+Cardio not the weight aids. A lot of people seem to think they can take clen, T3 or even DNP and become 6% bodyfat, but that just does NOT happen.
