Hi there everyone, i recently recieved adex from monster labs and had some serious sides. Elevated heart rate , high anxiety, shakes , maybe heart palpations, and possibly afib. I took .5 mg. The sides lasted 6 to 8 hrs. I notified them and they sent another pack but its from the same batch.. i have and taken clen before. These side were completely different.. has anyone else had any issues like this ?
