Low dose is the way to go. You will make great gains for several cycles doing that, as long as you keep training hard and eating right.
Most guys just use more drugs to replace their lack of brains. That is they are lazy, dependent on steroids, and do not adapt at all in their diet or training....they just think more is better and that steroids are the only answer.
Another thing to consider is you will not grow forever no matter what you take, so be realistic about your expectations. The body does not adapt or stop absorbing steroids, it just can only grow so much. If you have a headache 800mg of motrin will help, so taking 80,000mg is better right? That is the logic you have to avoid at all costs.
