Thanks for leaving a review! We're bummed to hear that Alpha Brain Black Label did not work as you expected. With a supplement like this, it can take some regular use to really feel the changes.That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our customer experience team, they'd be happy to help further!
