Yeah they are gullible morons that can be tricked into believing literally anything.
Honestly sometimes it scares me how easy it would be to make money with various scams. It’d be so easy to come up with a scam suppliment with the correct mix of pseudoscientific bullshit with some heavily implied but legally non explicit nods to popular conspiracy theories. As for ingrediants you just need water, starch, caffeine and whatever mystical/rare sounding bullshit you can find.
