    It is very good for me to counteract the effects of caffeine but it completely cancels them out for my wife. Fast shipping and well packaged.

  • Wonder

    Carlos 27/05/2025

    What an incredible product, despite the price it comes in enough quantity for many shots, it is important to keep it well, I spent some extra money to buy an airtight glass jar with easy access to it. I do not recommend taking it at bedtime as it causes some people to have vivid dreams and wake up as in my case.
