dbol and anadrol are going to be the best compounds for bulking... deca would make the list but these two would be the better overall options but in terms of cleaner type gains, then deca would be a better option

there is a big difference between hopping on a bunch of dbol, anadrol, and test and bloating up 20 pounds and actually putting on keepable mass.
