Many things stack well with test considering it, in most cases, is the base of any cycle. Your goals are really important when chosing what to stack. If you are just trying to get blown up then dbol and deca would be a good choice. If you are trying to get ripped, tren and primo. Check out the sust profile on the site and read some of the stack/use section if you already haven't. Oh yea, and stats/goals would help in determining dosage/stack.
