i would not use both together. its a perfect environment for excess dht in your body and you dont want that. also, proviron will suppress your natural test level further more because it is a strong androg on its own. ive used proviron and man oh man does it increase your sex drive, also you will get your jizz volume up on it too! i would use femera on its own. the only reason i would ever use proviron again is if i for some reason am not including test in my cycle and want to maintain my sex drive and erections (say if i was going to do something like deca and winny).
