FREQUENTLY ASKED QUESTIONS
How do I know X will work for me?
Every one of the 17 active ingredients in X has been proven through clinical research to benefit brain performance.†
What that means is that most people will experience a significant benefit.
Diet, exercise and sleep will also have a great impact on your brain performance.
How does X work?
Each active ingredient in X has its own mechanism of action, which has been proven to be effective in clinical studies.
Many of the ingredients boost levels of neurotransmitters such as dopamine, noradrenaline and acetylcholine—all three of which are critically important to focus, learning, brain energy and memory.
Is X safe?
We formulated X using the highest quality ingredients available.
It contains no harsh additives or stimulants.
Every ingredient has undergone rigorous testing, and every batch of X is thoroughly tested to ensure it is free of impurities.
How long will it take for me to feel the effects of X?
Most people experience a benefit within an hour of taking a full serving of X.
The full benefit will be achieved after 2-4 weeks of daily servings.
We suggest taking it for a full 30 days before judging its effectiveness for you.
How does the price per serving of X compare with other products?
The price per serving for X is considerably less than Alpha Brain® Black Label or Qualia Mind®, even though X contains a much larger number of active ingredients than either of those.
X is more expensive, per serving, than most other brain supplements.
X is packed with ultra-premium ingredients to maximize the benefit on brain performance.
X was formulated to be the best, not the cheapest.
How much is shipping and how long will it take to get to me?
If you purchase 2 or 3 bottles of X, standard shipping to the continental US is free and takes 3 to 5 business days.
If you purchase just 1 bottle of X, standard shipping to the continental US is $5.
You can also select 2-day shipping at checkout for a fee.
In rare cases (less than 10% of the time), 2-day shipping will take more than 2 days to arrive. (If that happens, contact us, and we'll refund the shipping fee.)

Quality and Standards
X is made in a state-of-the-art FDA-registered facility in California, which has Organic Certification, Kosher Certification, and is certified for Current Good Manufacturing Practices (CGMP) by NSF & UL.
Every batch of X is third-party tested for purity and potency.

Your satisfaction is our top priority
We will do what it takes to ensure that you are completely satisfied.
If you don’t love X, simply send back the unused portion for a full refund.
You can even use it for a full month and then send back the two empty bottles if you’re not thrilled with the results.
