I don't do a lot of reviews, however, after listening to these guys on the Ben Greenfield podcast I had to try this product. I am not on the ketogenic diet but wanted to see if I got an increase in energy. And it certainly delivered on that. All I use is one capsule in the morning and I like the energy I get from it. I have tried so many pretty workouts and they never left me feeling right. While this is not a pre-workout I like the boost. Great product.
