hearsay by itself is not enough for pc, it must be corraborated with other facts it get an arrest or search warrant issued. For example, say I'm 5/O and some gym member comes up to me and says that so and so is selling steroids in the gym, I can't go arrest that person or search their home soley based on that information only. Personnally I would go train at another gym, DO NOT TALK TO ANYONE, EVEN SO CALLED FRIEND ABOUT STEROIDS IN PERSON OR ON THE PHONE. I have seen many people go down on wire taps on cell phones and wires on so called friends. Good luck and stay safe
