Arnge crysh is just a N02 supplement like Amplify. You have your receipt? Just take it back and get your money.
Oh, and those GNC reps are douche bags. They get commision on sales, and tell get you to buy into their bullshit.
I had a guy at GNC tell me the ANATOR fro muscle tech is the best out there. I asked him if he used it, and he said yeah. Total bullcrap. Guy doesn't look like he's picked up a weight in his life so how the hell would he know what actually works?
