K first I have to say the taste is pretty awesome. A little sweet for my personal taste but still a good flavor of peach and tea. (one thing I do know is good tea). The label says to take 30 min before work out. But I would cut to 15 if on an empty stomach because I did that right at the end of shift before heading to the gym and in 15 min I was raring to go. Needless to say the drive to the gym was interesting. About half I got the tingle from beta alanine. This is one of the few prewo that I have actually gotten a a rush type feeling. Not overpowering but definitely there. Once at the gym I settled into my workout (chest day) had a nice energy through out. Didn't seem to wane at all. I left the gym with a nice pump in both my chest and tris. It's about three hours post wo and I still have a little pump in both. All around IMO great little prewo. Definitely on my Christmas wish list. If santa doesn't come through then I guess I'll have to buy a tub on my own. I'll try another flavor too.
