Picture of my insanity:
I won't say it's amazing but it does taste good and it's highly drinkable. Even for me, and I don't like black coffee. I like a little coffee with my cream and sugar. I don't know if my butter is from grass fed cows. I hope so, the poor cows are healthier that way. No idea. It is unsalted. And it's not upgraded coffee, it's Fair Trade coffee from Aldis.
I'll let you know if it's 'bullet proof' but keep in mind I'm on Alive vitamins and I keep guarana supplements in my desk drawer at work.
