Some serious pump here! I take three little scoops mixed into a glass of cold water on an empty stomach, and then chase it down with another glass of cold water because it is rather acidic tasting. Not terrible, but also not something I want lingering in my mouth and throat any longer than necessary to get it down to where it can be absorbed. I noticed some good side benefits, like less brain fog, and better performance in the bedroom, if you know what I mean. This stuff will pump up your blood supply for sure.
