“Hey folks, I have founded my latest venture. My creation for the $90bn per annum energy drinks category. However, it is unlike any other. It is the ONLY energy drink with 5 grams of the ketone ‘BHB’ inside. The ‘energy’ ketone (Google BHB). I also have this ketone patented. Meaning, while all the sleeping giants in the category have just been caught off guard by the MAC, they can do nothing about it! MAC ENERGY IS HERE! Enjoy, Beverage Forum, California! That’s how it’s done!”
