haven't used that one, but this:
it's probably pretty much the same thing, but with a catchier name haha!
first time i used it i didnt have any big hopes, thought it was mostly a hype thing and fake testimonials on their site.
but after maybe 40 minutes after taking it i all of a sudden realized i had gone from laying in my bed, a bit hungover and chillin out, to standing up and talking pretty fast to my friend and i didnt really wanna stand still..!
of course i had to jump on the bike and unleash it on the weights
as you said, you feel like you can lift more and heavier but i think the real winning is on those days you just feel like SHIT and your body refuses to even think about hitting the gym. a couple scoops of that and you'll be down there in no time..
