I brought up that I used ECA stacks before and had awesome results. He explained to me the only side effect from them that is bad is not long term unless you use them for a VERY long time.
The only real danger is working out (cardo) extremely hard while on a stimulant. It can cause a stroke, heart attack or heart murmur.
I wanted so bad to bring up AS but did not, I think he could tell I have used them though cause he did bring them up briefly but did not go into detail.
One thing he did say that was new to me is about dieting. He said your body can turn Protein into glucose and keep your muscles from depleting so the lower the carbs the better, as long as its not for a long time.
