The best!

On my second bottle and I love them! The results are awesome obviously along with working out but definitely worth it.

Burn Stack for the win!

Amazing appetite suppression. I've lost 8 pounds in first three weeks.

Amazing and works

Best fat burner I have ever tried. Energy is insane but the real reason it works so well is the appetite suppression. I cannot diet without this anymore. It cuts the amount of willpower you need to diet in half

Great for appetite suppression

This stuff really helped suppress my appetite for a while. I lost 20-25lbs while taking it and working out 5-6 days per week. The energy wasn't anything to write home about, not bad, but not crazy. I definitely felt the thermo effects though. I got my haircut before going to the gym one day. I took 2 of these thinking I'd be in and out before it hit my system. Nope... I was sweating bullets in the barber chair. Right now I decided to cycle off of it for a month because the effects on my body is diminishing. I'm thinking my body adapted to it and break will help. I will definitely be taking this again though. It's good stuff.
