Hi. Just wanted to ask what's in the title. Is adrenochrome a physical substance of some sort? I don't really understand what it means to "harvest" adrenochrome from kids. If someone could explain, I would appreciate it!

Edit: thanks for the responses! And for those calling me a glowie or shill for wanting to understand this concept, fuck off! I am a patriot just like the rest of you and am not fully in the know about everything! It’s normal to ask questions! For those who were kind enough to answer, I appreciate it.
