Why would anyone use prohormones when you have steroids and SARMS. PH's will cause basically the same side effects, if not worse, as steroids, but will not render the same results as steroids will. However, both of them are illegal now, so it is quite pointless to use prohormones in such case. On the other hand, SARMS may not be as powerful as steroids are, but they have no side effects at all, so you have a choice of either facing side effects in exchange for good results, or getting decent results without side effects.
