I'm currently in week 5 of 10 sustanon 500mg/week inj. every mon/wed/fri....I'm adding Masteron (Drostanolone Propionate) next week for 6 weeks at 360mg/week every mon/wed/fri too. My question is, can I mix the two in the same stick and poke at the same time? I'm guessing yes, just making sure this will be my first stack of two compounds. Also will this help with some of the inj. pain from the sust. cause this kinda sucks sometimes?
