Yeah, I did a cycle of kre-Alk for 30+ days, at 2.2 grams pre-workout. It took a couple days to notice a difference in strength/pumps, but when they did it was excellent, very good pump and vascularity throughout the day and especially workouts. I kinda jumped on the CEE bandwagon but next week Im switching back to kre-alk. My honest recommendation is that you try it, and keep a log on it. Everyone who is wary of kre-alk would definately be interested in your progress should feel so inclined. Yeah, transformers rule!
