Calisthenics/Streetworkout

I tried C4 extreme today, i went to the park, perform 20% better then ever. Straddle planche with straight arms and parallel line; all that shit, 10 times in a row for 3+ seconds. Probably the best workout i had. But now when i got back home i feel like shit, i'm dead. My heart rate is 100-120 now and i'm resting, i have chest pain, headache too, i feel like i'm going to die, if i fall asleep.
Never try any of those pre-workouts, trust me, it will work 2-3 times, then suddenly your entire life will be fu**ed up for days, you will feel desperate, sometimes agressive, i just read that they put some kind of drug in this shit.
