Hi, I am a rookie in terms of knowledge of deca, so i wanted to get some advice. is there an estimated cost deca costs on the black market? i am looking at a 10-week cycle and the guy said it is a 10 cc vial? also would anyone reccomend stacking the deca with any sort of test? i am about 5-11, 150 lbs, 32 yrs old and would like to add some mass to my frame. thanks for your help guys
