Taste is great. Takes 20-30 minutes to get the tingling sensation. If you’re new to this start with a half scoop. *

Decent flavor. Solid Product. Preworkout isnt essential, but it's got what you want: caffeine, beta alanine, and a little creatine. Gives you a little boost of energy which is really the only thing you need from a preworkout.*
