hi im 19 male im around 175 pounds about 5'11 around there iv been thinking about doing a cycle with a friend of susstanon 250 or how ever u spell it but im kinda concerned with health issues with my heart as my mom had a heart attack and her father had 3 massive heart attacks wen he was alive and the family has a bad past with heart attacks also my dads brother recently had a heart attack and he was the youngest of them all so maybe its on both sides im not to sure i also feel like my heart is beating slower then normal i think but if i smoke it shoots up and hurts a bit so for that i am qutting also i have really bad joint problems and most likely am gonna have arthritis wen im older wen i work out sumtimes my heart dose kinda hurt like my left side but i just ignore it so if sum1 can please give me some info? or advice right now im leaning to not do it as i dont wanna die just to get a bit bigger i think if i took the time and did it naturally that it would be a better choice and of course it is but should i be concerned about these health defects or w.eappreciate it thank you for ur time
