Pretty good starts to taste goofy after a while but good pump good energy de a very good pre dissolves and mixes well only other downside is the container can break easily if knocked too much in a bag

Okay
Big CBum fan, I wanted to like this more, but the flavors ain’t great. The formula is solid and effective, if you care about flavor I’d look at ryse or batch 27. (I tried the 3 Peat and rocket candy)
