hey, anything can be used for anything. dbol and deca can be used to cut. winny and tren can be used to bulk..
when it comes down to it, sure some are better suited for cutting and some are better suited for gaining, but in the end its all about what training cardio and diet anyways.
to the original question = ive got no experience with primo. however, its an androgen and extra androgens cant hurt

. there might be cheaper and/or more effective drugs you could takle instead, but i wouldnt know. "smoke if you got em" if you know what i mean
