While it's obvious to the trained eye, the people that are gullible enough to think that these overpriced supps will make a huge difference just so happen to be gullible enough to think that the sponsored athletes are natural and that they actually use the products.
The "athletes" get stick for not admitting to drug use but, at the end of the day, the second they admit it they'll be dropped and never sponsored again because the companies need people to believe that the physiques are a result of the use of their products. Though, guys like Simeon Panda who go out of their way to pay people for rigged steroid tests are the worst type of fake natty. It's one thing to deny, it's another to outright deceive.
