Caffeine always makes me feel like my heart is going to explode and I feel waaaay too jittery. I want something that is going to get me focused and in the zone while I'm at the gym. I know caffeine free ragnork is there and the stim free Blue up looks like it could do the trick. Any other good ones??
If you are not looking for Stimulant based PWO drink then the question becomes what exactly are you looking in your drink? From the top of my head I beleive you want a PWO with:
a) Some NO based products.
b) Stuff like Citrulline Malate, Beta Alanine, Taurine, Norvaline etc.
c) Loads of BCAA/EAAs.
d) Creatine of sorts.
My suggestion is why dont you save money and make potent PWO yourself? I suggest mixing the following :
Xtend/Purple Wraath
MAN Body Octane/ Geeen Magnitude
Bulk Products- NO, Citrulline Malate, Beta Alanine, Cissus.
This will make a product darn more potent than most stuff out there, will save you money...and also tell you exactly what works for you.
Plus that extra BCAA/EAA will help you through a real gruelling schedule.
Good luck.
