hi all.
let me be clear.
i've done cycles before for about more than 10 times in past 5 years.
4 months ago i was in a cycle for 4 days(actually i injected the starting dose)
and in the 4th day i came home.ate lunch drink cup of coffee and unfortunately i smoked
Edited after i smoked that
Edited i had panic i guess and i thought i am dying then feelings like heart attack came to me 2 or 3 times.and my heart rate rose and this came to me 2 more times.and i went to 2 good doctors and one said i have a disease that is with me since born and the other said it is a panic attack.the doctor said dont drink coffee or tea anymore.but i drink them and nothing bad happens to me.now after 4 months i have only some minor pains in my chest and this occurs when i think a lot about my heart

.and my blood test was normal.
THE QUESTION IS: if i start a cycle would it be harmful to my heart?and will i experience those things again?
thanks
