OK chemistfag here, and I'm calling bullshit on adrenochrome, here's why
Look at this molecule. This does NOT look very hard to synthesize.
I cannot believe this can only be made by torturing people.
Now maybe they did that back in the legitimate days of vampires, like 100 years ago plus. No question our rulers are vampires and I don't doubt they would do it.
But today, this is an easy chemical to synthesize. And there's no way that this is being made by the methods described, today.
It's not super-easy - having 2 ketone groups on a partially delocalized 6-carbon ring. And most likely it has entantiomers, and only 1 of the entantiomers has the desired effects.
But still, we can make structures like this relatively easily today.
I do think that Bidan raising the price on epipens is relates, because adrenaline/epinephrine is a precursor, and I don't doubt that these vampires are hooked on this stuff.
