We know nothing about your friend, so it would be stupid to assume that anyone on this board can give him the proper advice. We don't know his medical history, his problems, his body type, whether or not he has kidney issues, liver issues, any allergies, and he's 60 yrs old...which means he could be taking special doctor prescribed medication and dbol may really hurt him....
Let alone thta he has no clue about steroids and hasn't cycles before...and for all we know doesn't work out right now...
I think the best advice anyone could give you is to go see a doc...well, your friend should go see a doc and get some medical advice...he can probably get away with test which is a much better alternative at his age and for what he needs to do
