[|Human|] Hi. I have been taking pre workout (C4) for the past few weeks and I am having trouble breathing. I have to concentrate to breathe. I have chest pains. Its very hard for me to fall asleep because Im concentrating in order to breathe. Is this normal? Can I be developing asthma? These symptoms do not come and go.
[|AI|]  Hi, The pre-workout (C4) you take contains creatine nitrate to give you extra energy.  Creatine itself might induce asthma development. So, the difficulty to breathe and sleepiness due to short of breathe are signs of asthma, which is induced by creatine of pre workout (C4).  I strongly suggest stopping taking this supplement and contact your physician as soon as possible to get further evaluation and adequate treatment.  All the best! Chat Doctor.
