Hello there, I am 177CM tall, 21 years old (around 83KGs) and 20% bodyfat, I have a great amount of muscle tho. I have taken my first dose of 40MG clenbuterol pill 2 days ago, I actually felt extreme body heat and I was sweating a bit, I than began having a little chest pain and shortness of breathing, I was sitting in the air-conditioner and still feeling extreme heat. I catched a fever and throat fever (coughing, and sneezing) and having a runny and blocked nose for 2 days, I immediately stopped taking clenbuterol. same as a high heart rate (when i was sleeping, i feel my heart beating fast that scared me like shit) maybe thats because its first introduced? or that i took 40mg as a first time with caffeine? or maybe thats because i was extremelly hot and exposed myself to the air conditioner? I do not know whether i should continue or not. I have stopped it for 2 days and i began healing already. Please tell me if I should start again on just 20mg/clenbuterol for 3-4 days and increase to 40mg and stay there? or should I just sell it? I do not want to die, thank you.
