15 mg eod dbol is a waste. Tren at 200mg/week is a little low but could be used. I would strongly suggest that you hold off on starting anything until you can get more dbol and test to run as a base. Also take some time and planout your PCT. Do not simply run two drugs together because you have them.
Tren and dbol pair well and are a great combo when used properly. Clearly sneed you are undereducated. Research your products and find out how often and in what quantites you need them. Finally considering adding test and find out why.
