i've used ON for a while now.....and i have always wondered why it's $17.99 at the biggest rip off place in the world....GNC. this is disconcerning....to be quite honest i've had better results with other proteins in the past.....MHP has great products....but unfortunately they are more than double the price so it gets too expensive with how many shakes i drink during the week..... pretty much the only reason why i use ON.....
