I have been using Black Cats for a while and I like the kind of energy it gives me, but I have some samples of RPM and I would like to know if it is a good idea to stack 3 caps of RMP with 2 caps of Black Cats. Also, I just recently started taking DAA + Erase. Is it safe to take RPM with DAA and Erase? And aside from safety, does it make sense to take RPM with DAA since both raise testosterone levels? Can one interfere with another? I am sorry for so many questions, I just want to do it right. Thanks.
