Stiff-Lips: The thing I never knew I needed.
I dont even know where to start.
I'm a highschool student struggling through the last year of school and let me tell you, I just got these today and I tried one when I wrote this review. I'm going to be able to survive my last year because of this stuff.
Stiff-Lips is one of the best preworkout and caffine products I have EVER purchased and it ACTUALLY WORKS. while the taste is something to get accustomed to, its perfect.
Thank you.

Just a flavor pouch is all it really is. No stimulation.

Sour, and the pouch is REALLY big, but it tastes really good. Like juct fruit gum but it lasts more than 5 secs.
