Insane Focus
Overall I really love this pre workout. I have taken it before martial arts class, HIIT class, as well as weightlifting. It excels for martial arts class as the focus is absolutely insane. I'm able to learn new techniques with ease and be able to do them very well almost immediately. Complete game changer
