Just a real quick review:
I'm on my third or fourth week. Dosing one every morning with 60-80g carbs, except for workout days which have been limited to 3 a week.
Workout pump has been pretty good, but my perpetual pump has been great! I feel pretty pumped today, even though my last workout was Wed.
It's simillar to AP, but the effects there diminished somewhat towards the end.
The effects have definately been cumulative, increasing every week. I'm considering getting another bottle. Anyone curious should try it IMO.
