Let me start by saying I want to limit my ingredients to 3-4, caffeine probably a must. My main goal is energy &for cardio (playing full court basketball in my case) in the evenings. Not concerned with the "pump" that some look for when lifting.
After doing some searching on internet for ideas, here is what I came up with...
1. Caffeine powder
Loved dmaa (Jack3d) in the past for basketball but really tuff getting to sleep (plus the ban thing). I tolerate caffeine much better in this regard.
Have I "nailed it" or something better for one or two on the list? (Remember, I really prefer limiting to 3-4 supps only.)
