Suprisingly i have been on it for several weeks and have noticed a difference in my stomach and legs. I havent lost any weight, but i have lost some fat. As fast as i lose fat, i gain that much more muscle. I was suprised at first because their arent any side effects as compared to Ripped Fuel. I have taken Ripped Fuel in the past, but not for weight loss. I used it as a stimulant to stay awake in the mid to late afternoons when i use to hit the books hard. I always took it with food so it went into my system slowly. Without food your heart would race, this is what i expected from Hot Rox because it says to take it on an empty stomach. Fortunately that didnt happen and it seems to work for me.
Dont pay more than $40 a bottle though.
good luck,
corey
