I've been a coffee professional for years and understand coffee chemistry, food science and biology. Black coffee on its own has significant health benefits. If the component chemicals in mushrooms were truly a revolutionary leap for anti-aging or anti-cancer, then we'd see a whole lot of mushroom products on the shelves
at GNC and not just in coffee.
Not to mention, mushroom coffee is a popular MLM product because it has no market in regular retail. It needs shysters to sell the crap.
If you really want to argue with me on this, I imagine you're ripe for paying a substantial amount for penis enlargement contraptions.
