Powder: mix one serving into a glass of water and drink. Take Brain Stack in the morning or before a long work session, Acne Stack at any time of day, and Sleep Stack 30 to 60 minutes before bed. Capsules: open one daily packet and take it with water, at home or on the go.

It depends on the stack and on you, so we don't promise a timeline. Each stack is made for consistent daily use: Brain Stack in the morning, Sleep Stack 30 to 60 minutes before bed, and Acne Stack any time of day.

Yes. A common routine is Brain Stack in the morning and Sleep Stack at night. Brain Stack contains 100 mg of caffeine, about the same as a cup of coffee, so keep it to the first half of your day and factor in any other coffee or energy drinks. If you take medication or are pregnant or nursing, check with your doctor before starting any supplement.

Every stack is 100% vegan, non-GMO and gluten-free, with 0g sugar and no artificial colors. Every ingredient and dose is printed on the label, with no proprietary blends, and every batch is third-party tested for purity and potency. Sleep Stack is melatonin-free.

Same goal, different format. Each powder jar holds 15 servings you mix into water. Each capsule box holds 30 daily packets you take with water, nothing to mix and no flavor.
