Clen and cardio

[blackbird]

Hi does anyone know if Clen helps or hurts cardio performace?
You would think in small doses it might help since it was originally made for astma.Thanks

it helps me. I get on high dose of clen for my contest prep and i can breathe better and feel better.

anyone else notice that clen makes their joints hurt? I was using only 40-50mcg a day and it felt like my wrist were dry as hell. I stopped and within 3 days all joint discomfort was gone

Clen is very similar to tren for me cardio wise. I get out of breath easier but despite this cardio seems much easier to get into, more energy and will to do it. Im not a fan of cardio at all, only part of bodybuilding i dislike, but i dislike body fat more

what about with weight workouts? does it act like ephedrine as far as a stimulant?

I'll tell u that even a low dose of 20mcg makes my cardio heart rate increase massive for instant stair mill at level 3 heart rate 130-135 bmp no Clen, with Clen same level 3 150-155 bpm.. Cant stress enough go easy on this stuff, more is not better..

I am finished with clen. I actually threw out my tabs. I'm not able to handle 20mcg any longer. It gives me the jitters so bad that I don't feel like working out. However, I was an excellent fat burner when I used to take it. There has been to much info circulating as to whether clen is good or bad for your heart. Well, I'm not willing to take the chance.
