Great Boost
I workout at 4:30 a. m. and start the session with my Frog Fuel. My outcomes change for the worse if I forget to take it. That hit of caffein gives me just enough energy until my natural juices start flowing. I use before lifting, rowing, and walking.

This version of the Frog Fuel Pre-Workout is a step up from the previous non-caffeinated versions from before. The pickup is gradual, sustained, and doesn't peak too early in the workout. I am 55 years old and swim 2-3 miles in the pool every morning and have plenty of energy to keep up my pace and bring home the final laps. I follow this with the protein packet right after to begin recovery as well. I won't use a different preworkout ever! I've spent thousands and never found what this has. Good work FF! Hooah!

It is my second favorite pre-workout overall, but it is my first favorite for volume and conscience.
