It's bullshit.
The shitshow on Rogan's forum when this first came out was hilarious.
Aubrey/Marcus/Thundercock whatever name he is using these days got his start selling plastic vaginas and nail polish for men. And he also ran phishing sites.
When he first came out with this snake oil, he had recommendations from a medical professional on his site. He was outed-it was his mom. And she was a doctor of oriental medicine or some homeopathic bullshit.
When he first started selling Alpha Brain, people got sick, and he revised the formula. When people called him out that he had no credentials in something which is supposed to affect cognitive ability, he called them fat fucks etc. He hired people to go on Joe's forums and leave positive reviews. Joe banned people who called the snake oil snake oil.
People found the "lab" where this shit was made, and it was like some hole in the wall where a bunch of Chinese indentured servants worked, lmao.
But seriously, the name of the products and the people behind it should be enough to keep you away.
