Lots of the old timers did d-bol only cycles with great results. It may not be the best way to go, but you can get good results if you train and eat right. It's funny how people say they get great results from some prohomone but guys will knock bol only cycles. D-bol kicks the living snot out of any pro-hormone!!!
But make sure you take an anti and get liver protection like N2Guard. Some Liv 52, tudca and protein factory POSTCYCLE wouldn't hurt either. D-bol is very hard on the liver.
