Used it to run upto boxing fight more the the energy for the extra sessions not the fat burning
I did lose 14lbs while using these but I was also training an extra 3 hours aweek on top of my usual 5 hours.
It says take before food, I found this left a werid warm feeling in my stomach. Took it with breakfast instead of before and was fine.
Great to use as a pre workout if you every forget yours but if you take too late at night means very ull be awake in the the early hours.
When you first take them you feel little bit shakey and sickly.
I found they didn't suppress my apatite but whilst taking them I was still stuffing my face with junk and my weight didn't increase. I have a slow natural matablisim.
So with will power they work.
Don't take them to late in the day or you will be up all night.
I think they are good don't be put off by the funny feeling you get it lasts around 20 mins and after two days of taking them it went away.
