My household buy 144*2 bottles of 2.0 a month.
It’s you! You win!
I bet companies buy the most, and from individuals probably athletes and bodybuilders.
I almost always drink 5 bottles a day. (Actually it’s 4 because I’m getting rid of my old DIY for one meal a day.)
I would like to get my wife into it as well. She won’t touch the stuff. Says it tastes horrible but she hasn’t tried it. I keep telling her that she tried my DIY but she “knows” she is right. Oh well.
