Adrenchrome is kind of a meme, misdirection, or not a completely accurate depiction of what is being done. The elite do harvest young blood and fluids saturated with HGH. Adrenaline and psycho-active chemicals from the pineal and pituitary glands to transfuse in their own bodies. The steal organs as well. People like Soros and Rockefeller didn't simply use state of the art health care with their infinite wealth. The ultra rich want to live as long as possible as their primary goal. There are studies from young and old mice spliced together and it reverted the aging process of the old mouse. Its insane.

There are two paths of Kaballah. Its taught in the highest eschelons of Freemasonry that if you treat your body as a temple of God you can activate and "baptise" your Sacred Seed naturally. The pineal gland, pituitary gland, and claustrum all work in tandem to secret oils which get transformed in your solar plexus and then returned to the claustrum for seemingly super human mental processing abilities and regeneration, anti-aging etc.
The Satanic elite stray from godliness and steal those from young children and follow the left-handed path. Its the faster method of course but getting them from other sources turns off your own natural production so its a double edge sword if your supply is cut off, and its evil of course.
