Frequently Asked Questions

Ordering, formulas, shipping, and promotions.

Ordering & formulas.

How do I choose a formula?

Choose the available formula on the product page before adding it to your cart. Capsule options use black-bottle artwork; liquid suspension options use white-dropper artwork where that formula image is available. Check the selected formula in your cart before paying.

How does the custom stack work?

Choose any three eligible individual products for $199.99. You may repeat products. Existing stacks and bundles are excluded. To change selections after adding the stack, remove it and build it again.

Can I edit my cart?

Use the quantity controls and Remove buttons in your cart. Exclusive offer items are limited to one discounted unit per product. Custom-stack selections stay together as a group.

Coupons & exclusive offers.

What does SAVE10 apply to?

The newsletter’s SAVE10 code takes 10% off eligible normal purchases, including sale products and stacks. Items added through the exclusive 55%-off offers do not receive this additional newsletter discount.

How do the 55%-off offers work?

Add an eligible regular or regular-sale purchase to unlock the offers. Offer items are priced at 55% off their regular retail price, with one discounted unit of each offer product per cart. Offer items cannot qualify themselves. Removing the last qualifying purchase removes the exclusive discount.

Where can I enter my coupon?

Use the coupon field in the cart drawer, cart page, or checkout. Review the final item prices and order total before payment.

Shipping, tracking & returns.

When is shipping free?

Eligible U.S. orders of $100 or more qualify for free shipping. Checkout shows available methods and eligibility. Other destinations use the applicable checkout rates.

Where is my tracking number?

Tracking is emailed after shipment. Check your spam folder, then contact support if you need help locating it.

How do I request a return?

Contact support within 14 days. Items must be unopened. Review the Returns & Refunds policy for fees, exclusions, and instructions.
