Hi, when i workout or perform cardiovascular activitys i have a heart beat of about 120-150 , if i take a supplement called Jack3d which is a pre workout supplement, should i worry? i heard it may give you a faster heart rate but if its nothing to worry about then im fine.
Hello, I have gone through your query. Thanks for using Chat Doctor. Normally there is always increase in heart rate in response to exercise. So you should not worry about increase in heart rate with exercise. But Jack D3 has many side effects including palpitations and heart attack. So better avoid it, My best wishes Chat Doctor.
