Im new to this site and would appreciate a bit of help. Im 30 ys of age 165 pounds/75 kilos. 6ft1" so im a very thin person. Im going to start on my first cycle in a month or so i have sustanon and test prop. Is this a good combo if im looking for definition and to bulk up a bit? If i was to keep the sustanon and change the test prop for something else what would be good for me? Would deca be a good match with the sustanon for me? Thanks.
