High Quality Product
This product has been pretty great. I have ADHD and this does help me feel a bit more balanced over using traditional caffeine. I will be trying other products from Sports Research.

Honest Product
I purchased this product a few weeks ago. As a busy Nurse, I needed a healthier option for energy than the expensive drinks. Not to mention the headache's I get from other energy products. This product is everything it claims to be! Thank you :blush:
