Hell no, are you crazy? do NOT electrify your self man! that's dangerous shit!
the voltage the ROP creates is extremely low, don't exceed it by putting batteries there or something... lol
I suppose you don't understand how the ROP works, so I'll explain: since both Zinc and Copper are metals they have different potential levels (I dunno how to say this in proper english.. that's how it's said in my country), since electrons are negative they seek higher potential than the metal they're already in and "migrate" to the other metal, this process creates a flux.
The idea behind the ROP is that a tiny winy amount of Zinc will migrate with the flux going through your balls and it's considered more efficient than supplements because the body finds this normal and doesn't react negatively.
The electricity which runs through your balls SUPPOSEDLY makes them generate more testosterone AND makes them bigger...
some people say it worked for them, I think Supra even claimed that his testosterone levels have increased which he proved by a testosterone test he did, but consider the fact he was working out and taking supplements..
it may just be them thinking it did help them, after all.. it's all in your head mate..
Now that you understand, do not hook up batteries there! lol
