I have heard about Arnge Krush, but it is expensive and it has creatine in it I don't want something with creatine becaue I am trying to lose weight and I don't like the water retention. I tried taking NO when it was new back about 5-6 years ago, but figured it was too expensive for the limited gains. I wanted to know if it has gotten any better since then and which are the best on the market? Also, what is good place to buy it on the internet? Is it worth the money or just a waste like NO2?
