im about to start a cycle of sustanon 300. ive done sus 250 in the past and it turned out ok but i want a little more info. should i be taking any kind of anti-estrogen or any other kind of supp for my hormones while taking the sus? Or should I just wait till the end to take my PCT. Also I dont know what to take for a PCT. Last time i just took a test boost/anti-estrogen in one.
