I'm not going to argue with idiots. Yes alchemy was hidden from weak minds like you, who literally wrote all that but did not disprove a thing that I said. Have you searched how melatonin has "fountain of youth" properties, which if produced/harnessed correctly can delay aging for who knows how long? Strengthen immune systems,prevent cancer,treat alzheimers(which is a disease that comes about when the substantia nigra stops producing that neruo-melanin in certain people when they get older.) etc. Maybe this is why Yale,brown,Berkeley,Harvard etc are studying day and night on how to make a synthetic form of it for those who can't produce much of it? See, you're going to come on here and talk out of your ass all because you're ignorant to the subject at hand, but still act as if your disbelief makes it any less true lol. It's not only melatonin that the pineal gand produces theres also DMT and a whole host of other hormones. You don't think those who run society know this? That's why there is artificial lighting everywhere you go, this kind of lighting halts many key functions of the pineal gland(look this up there are countless physicians all over the world who are up on this) and is the very reason Americans cancer rates are out of control! Hitler was a master occultist, that's why he used the swastika to represent his Nazi party, he knew "Aryans" weren't blond haired blue eyed people that was for the sheep to swallow, the Aryans came from Dravidian stock which were DARK skinned indians from the subcontinent of India. Do a bit more studying before you come at me man. I've been studying this for damn near a decade now, and I've chosen my words wisely as to not give away too many secrets to an ignorant mind such as yours. You clearly do not have the mental or spiritual propensity to understand Alchemy. This is why it has never crossed your path.
