Returns & Exchanges

Darko’s 30-Day Satisfaction Guarantee

We stand behind the quality of our products and want you to be completely satisfied with your Darko purchase. If you are not happy with your supplement for any reason, we offer a 30-day satisfaction guarantee for all non-subscription and subscription orders—no questions asked (subject to the terms below).

Eligibility for Returns & Exchanges

To be eligible for a return or exchange, your request must meet the following criteria:

  • Request is submitted within 30 days of the delivery date (not the purchase date).
  • Product is in its original packaging (unopened/UNUSED products for full refunds; opened/used products for store credit/exchange only).
  • All items from the original order are returned (including promotional items, if applicable).
  • Order was placed directly through the Darko website (we do not accept returns from third-party retailers).

How to Initiate a Return or Exchange

  1. Email our customer support team at darko@darko.company with the subject line: "Return/Exchange Request - [Your Order Number]".
  2. Include the following information: order number, delivery date, product name(s), reason for return/exchange, and your preferred resolution (full refund, store credit, or exchange).
  3. Our team will review your request within 1-2 business days and send you a Return Authorization (RA) number and return instructions (if applicable).
  4. Ship the product back to the address provided in the RA instructions—include your RA number on the shipping label (no RA number = delayed processing).

Important: We do not provide pre-paid return labels—all return shipping costs are the responsibility of the customer. We recommend using a trackable shipping method (USPS, UPS) to avoid lost packages.

Refund, Store Credit & Exchange Details

  • Full Refunds: Only available for unopened/UNUSED products. Refunds are processed to the original payment method within 3-5 business days of us receiving your return. Refunds may take 1-2 billing cycles to appear on your statement (per your financial institution).
  • Store Credit: Available for opened/used products (at our sole discretion). Store credit is added to your Darko account within 24 hours of us receiving your return, with no expiration date—can be used for any future Darko purchase.
  • Exchanges: Available for unopened/UNUSED products (same product only—no upgrades/downgrades). Exchanges are shipped for free (US only) within 3-5 business days of us receiving your return. International exchanges require additional shipping costs.

Damaged/Defective Products

If you receive a damaged or defective product (e.g., broken bottle, expired product, manufacturing defect), you are eligible for a free replacement or full refund (including return shipping costs).

To report a damaged/defective product: 1. Email darko@darko.company within 10 days of delivery with your order number and clear photos of the damaged/defective product/packaging. 2. Our team will approve your request immediately and send you a pre-paid return label (US only) or process a full refund (no return required for minor damage). 3. Replacements are shipped for free within 1-2 business days of approval.

Non-Returnable Items

The following items are not eligible for return, exchange, or refund under any circumstances:

  • Opened/used products (except for store credit, at our sole discretion).
  • Promotional items received for free (unless returned with the original order).
  • Products purchased from third-party retailers (Amazon, eBay, gyms, etc.).
  • Products with tampered/broken seals (unless the seal was broken upon delivery).
  • Products damaged due to customer misuse, neglect, or improper storage.

Subscription Order Returns

Subscription orders are subject to the same 30-day satisfaction guarantee as one-time orders. If you wish to return a subscription order, follow the same return process outlined above.

Returning a subscription order does not cancel your subscription—you must cancel your subscription separately (via your Darko account or email) to stop future shipments.

Lost or Delayed Returns

We are not responsible for lost, stolen, or delayed return shipments—we recommend using a trackable shipping method and purchasing shipping insurance for high-value orders.

We will process your return/exchange only after we receive and inspect the returned product (typically 3-5 business days after delivery to our warehouse).
