<s>[INST] i went to the doctor today and found out i have slightly high blood pressure (132/82). im a 20 year old college baseball player and i use hemo rage black (a pre workout supplement) to get the most out of my workouts.  is this okay or should i stop immediately? [/INST] Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your increase in the blood pressure seems to be related to the supplements you are taking. You should know that all the pre-workout supplements have shown to increase blood pressure and cause cardiac arrhythmia. But also other secondary causes of high blood pressure should be excluded too. I would recommend consulting with a GP for a careful physical examination, a resting ECG, a chest x-ray study and some blood lab tests (complete blood count, thyroid hormone levels, cortisol plasma levels, kidney and liver function tests, blood electrolytes, etc.). Meanwhile, I would recommend stopping all the supplements that you are taking. Hope to have been helpful! Greetings,  </s>
