4/5
I've used plenty of preworkouts over the years & this is definitely one of the more aggressive products I've tried. Great for charging hard, focus, intensity.
Definitely not for stim sensitive or the weak of heart, Maximize kicks hard. I found it best to drink half, then wait a few minutes before drinking the rest as it's easy to overstim on this.
I gave some to a couple of friends, warning them to start with half a scoop & take it easy initially. They didn't listen - bad mistake. Jitters, shakes, anxiety & several trips the the toilet to throw up ensued.
If you're a stimaholic then you'll probably love this. If you've got a weak stomach then avoid it. Start with half a scoop regardless!
