I keep white flood on hand as my old trusty standby. Always works, awesome focus.
Others I have in the cabinet:
Hemo Rage black -- feels too "stimmy"- like too much uncontrolled energy but one of the most powerful
1MR- very high in caffeine, 300mg. My workouts on this are intense and time seems to stand still. 90 minutes feels like 2 days, but its hard to stop before 90 minutes on this
Vasocor- solid, only available at one place, but reliable product
D-stunner is one of my favorites as well. Intense energy and focus, I feel unstoppable on it.
That's what's in my cabinet today. Depending on my feeling, I rotate the PWOs. I use hemo rage the least and 1mr next. I use white flood, vasocor, and stunner the most. I drink these at 430 am to destroy things by 515.
Others I've used are C4, super pump, no xplode, animal rage, and whatever else I can't remember. But I don't own these currently so that may tell you how i feel about them.
Stim addict? For me, its the difference between a 400 calorie hour and 800-1000 calorie hour. Yes, really.(heart rate monitor)
Hope this helps. I'm interested in Craze but never tried it. Also Clen is absolutely the best, favorite, greatest thing ever for me but that's not for everybody
