Ketoneaid KE4 Pro is super concentrated 50% Ketone Ester. 

KE4 costs less than premium ketone salts on a gram per effective gram basis. Many people use as little as 5ml of KE4 a day. The average person takes double that, so it would last them 18 days.

Elite athletes may use 1 bottle which is 30g of Ketone Ester (60ml of KE4), but that is usually overkill. Too much can be worse.

The "flavour" is called "Very Scary Cherry". It no longer tastes like rocket fuel but it still  doesn't taste great. More like cough medicine. Most are fine with it. If not, try diluting. 

* Ketone Ester is D- Beta Hydroxybutyrate/ D 1,3 Butanediol Monoester.
Other ingredients: Water, Allulose (non-GMO zero glycemic all natural sweetener), Organic Stevia, Natural Cherry Flavors, Potassium Sorbate (freshness).

Certified Drug Free and WADA Compliant. 3rd Party certificate available from Ketoneaid.
