I got a free bottle of this because of where I work so I thought I'd give it a try but price wise I see it's about 35 dollars on average which when talking thermogenics that's not so bad.

I definitely felt the heat from this product and it had a nice caffeine boost. Sometimes I took it in the mornings to wake up and other times took before the gym with my preworkouts.

It's one pill so that easy and nice. It's also a 30 day supply.

I didn't lose any weight but I liked the energy and maybe I shredded up maybe it's all in my head. Over all I think there are better ones, but this is a great starting one. It's nothing crazy only about 150mg of caffeine.
