90-Day Money-Back Guarantee

Within 90 days of delivery, you may request a refund on any supplement purchased from corelabs.co and shipped within the United States. The guarantee covers the product price of both opened and unopened bottles. Original shipping costs are non-refundable except where we made an error.

1. Email support@corelabs.cowith your order number and the reason for the return.
2. We send a Return Merchandise Authorization (RMA) with your refund amount and the return address.
3. Ship the bottles back using any trackable service. A first-class stamp is usually enough for a single bottle.
4. Refunds are issued to the original payment method within 5 business days of the package arriving at our facility.

Subscriptions can be paused, skipped, or cancelled at any time from your account — no penalty, no phone call. Cancelling stops future shipments; it does not refund orders already delivered, which remain covered by the 90-day guarantee. You can also change the delivery frequency of any subscription (every 15, 30, 60, 90, or 120 days) at any time.

If a bottle arrives damaged or you received the wrong item, email a photo within 14 days of delivery and we will replace it at no cost — no return required.

If your order is lost in transit and has not arrived within the quoted delivery window plus 5 business days, contact us and we will file a carrier claim and replace the order or issue a full refund.

The guarantee does not cover products purchased from third-party retailers, orders beyond 90 days from delivery, or shipping fees. Bundles are refunded pro-rata against the returned items. Orders with addresses outside the United States are not eligible, as we do not ship internationally.

We are committed to resolving every request fairly and promptly. Please contact us before filing a chargeback — doing so may delay your refund and can result in your account being suspended.
