Clen giving me chest aches..
So i did a 3 week run with clen, I got up to 120mcg and was feeling ok till the 3rd week i would feel a pain near my heart and got a lil freaked out and leaned off of it. So now i took another shot at it but even at 40mcg's im getting these weird aches like randomly. I have no idea why it keeps happening and its freaking me out. Im prolly going to stop it because i don't like the feeling it gives me near my heart. Just wanted to know if anyone else has had this also? there chinese ones if that helps 40mcg's each
