Adrenochrome is the theory that only though severe human torture and fear that the adrenaline of the human body can be made into the ultimate drug that only the elite consume. This basically explains it.

Many who believe this say it's been hinted in many different movies and shows. The movie Vile (2011) is about multiple teenagers who are kidnapped and forced to be tortured and mutilated in order to create Adrenochrome and escape.

The movie "A cure for wellness" is about an adrenochrome producing facility and the elites who feed on it to stay alive.

The show Weeds makes references to it. The Island does as well. Fear and Loathing in Las Vegas is a big example of it. A clockwork orange does as well.

A movie came out this year that's on amazon called Adrenochrome. This is the summary.

"An action packed thriller full of eye candy, deep meaning, wild motorcycles, machine guns, and much more - American Veteran West Walker comes to California to find a gang of Venice Beach psychopaths lead by a Charles Manson 2000 killing people to extract a psychedelic drug out of the victim's adrenal glands."

In the comments someone mentions the new video game Far Cry 5 has a character who mentions it.

I've researched Adrenochrome in the past and read many of the Pizzagate theories on it. Well I found a Medical Corporation who sells it.

"Sigma-Aldrich"

"Sigma-Aldrich Corporation is an American chemical, life science and biotechnology company owned by Merck KGaA."

This is a link to the sales page.

If Adrenochrome is real and connected to Pizzagate this corporation sells it.
