Liquid Supplements For Zitsfleisch

I am growing tired of using energy drinks as it is a lot of waste in plastic, having to go to the bathroom and WAY too much sugar. I am looking for supplements for enhanced Zitsfleisch as well as energy to work my manual labor job.

5 Hour Energy:

I am taking 5 hour energy as a stimulant for focus.

I don't want to get up and walk around every 5 minutes, I want a stimulant which is going to enhance my Zitsfleisch.

5 hour energy works okay and definitely gives you energy to move around in the morning as well as inspiration but not the DEEP focus I am looking for.
