RE: Whats making this guy pass out?
Why has this guy not talked to his Doctor if he is passsing out? Not being funny mate, but why would you not point him to a qualified GP? I know he is on the gear, but this could be something a lot more serious........
BTW, I also agree 100% with Toxic. The first piece of advice you should give any "Younger Guys" wanting to juice, should be to not do it until they are older. You are in a position of trust here, so get clued up sooner rather than later.
