Yes, everything they say about cortisol is true. This is how they sell their crap. They spew a bunch of science which is all very true and then make you think they have something that will work for it. And the kicker in this instance is they charge a whole bunch of money for it to make you think, WOW, if it cost that much it MUST really work. And it is no better ( not as good as some) than anything else on the market at much cheaper prices. What a marketing scheme.
