My favorite daily!
One of my favorite go to pre workouts! You don’t feel cracked but the energy keeps you going without a massive crash. I keep trying different pres but keep coming back to this as my daily.

Good choice
Great pre workout not that much an energy boost but it definitely didn’t make me crash after. The taste is great too I’d drink it all day

Not good
Probably the worst tasting pre I've had so far. Doesn't work well for a pre workout either. Felt very little from it.

Stopped using.
When I first tried this stuff, the focus was so intense, and it wasn't like most pre-work outs that hit right away, this stuff came on nice and gently, also you need to have the mind set of not waiting for a sudden surge of motivation to go exercise. It's down the hatch and get to it, once your in the start of your routine is when you'll notice it, the intensity, focus and energy that followed was incredible, however the last two I got ended up with the same sentation heavy in my gut and killing any motivation what so ever, turning my workouts into a complete struggle, not sure if the formula got tweaked or what, so I moved on, giving it three stars to be fair, people change, building up a tolerances, or change in diets. I'm not saying I'll never get it again but for the price and the amount of servings you get, it didn't make it viable for something that stopped having a positive effect on me.

Joke
A literal joke 😂 I've tried using this over expensive stuff for too long. I've never noticed anything. Definitely NOT high stim. No focus No jitteriness and the taste. . .it's decent.
