I started taking TestoFuel a couple of months ago and after two bottles I didn't really see much difference. I did a lot of research on Google and thought this would be the answer. Turns out it's not. I decided to look elsewhere and found that I've gotten more out of Spartagen than TestoFuel.
I wish I could be a little more positive about this but I just wanted to let you know the truth. I wouldn't recommend TestoFuel to anyone.
Bottom Line: No, I would not recommend this to a friend
