Returns / Refunds


Your first shipment will contain 4 unique blends of nootropics, each with 6 sachets of your daily recommended nutrient dosage. We encourage consecutive usage of 1 blend at a time, in order to eliminate any outside confounding factors. Log how you feel at the end of each day in order to identify the best stacks for your goals!

Depending on the nutrient blends and your metabolism, effects can take between 30 minutes and 3 days of consecutive use to appear in full. We call this a loading phase.

We recommend formulas based on your survey results. Everyone responds to nootropics differently, and not every formula may be effective. During your trial month, you’ll test and learn which blends work best for you.


You can adjust the cadence of a delivery, skip a shipment, or cancel your subscription at any time: reach out to our team for assistance, or simply make the changes in your account.


If you are not happy with your formula, reach out to us so we can make recommendations and adjustments! We are here to help you optimize your cognitive function, and are committed to identifying the nutrients that work best to achieve your goals.
