90% of what you were told about steroids in primary and secondary school is bullsh!t. There's no roid rage, and if you do not cycle all the year on very powerful stuff like Trenbolone, you will not have a heart attack.
I've used them in the past; I never experienced high blood pressure, heart problems, high cholesterol or any other significant issues. Only noticable thing is that the Deca caused some water retention. Compared to smoking or getting drunk every weekend (like almost everyone born after 1980 does), it does not do much harm to your body.
