I already have T3. I thought it was the better choice because from what I read its easier on your heart. Or has more room for error then Clen. And the shakes and sweats aint as bad. I know T3 eats muscle as well as fat. But I was under the impression it was safer so thats what I got. I am on Test E cycle now so around week 4 I will start taking it. I got a great diet and do cardio for a hour 4 or 5 days a week. Bike ride and play basket ball here and there. Any way, if Clen is harder on your heart why do so many obeise people take it instead of T3? Correct me If Im not right about the heart thing. I have been debaiting on even using the T3. I though I was around 18-19%bf but Im starting to think Im 13-15%bf after seeing people guessing others BF. I am going to check it this week. I know there are tons or T3/Clen threads and I read them all. And there profiles on many sites. I guess I just wanted to talk about them? Get some personal experience with people who used T3. Seems like everyone pretty much sticks with Clen. And all the T3 threads have no up dates on how the cycle went. So anyone want to B.S. about there T3 cycle or experience give a shout.
