Shipping Policy

Last Updated: October 1st, 2026

Double Diamond Peptides LLC (“Double Diamond Peptides,” “DD,” “we,” “us,” or “our”) maintains this Shipping Policy for orders placed through vantapep.com.

This policy should be read together with our Terms and Conditions, Refund and Returns Policy, and Research Use Policy.

1. Shipping Destinations

Double Diamond Peptides LLC currently ships orders within the United States only.

We do not currently offer international shipping.

We reserve the right to restrict shipment to particular persons, addresses, locations, or jurisdictions when reasonably necessary for legal, regulatory, compliance, security, or business reasons.

2. Order Processing and Fulfillment

In-stock orders are typically processed and fulfilled within 2–5 business days after order placement, excluding weekends and holidays.

Processing and fulfillment times are estimates and may occasionally be affected by order volume, inventory availability, carrier disruptions, holidays, weather, or other circumstances.

Customers will receive shipping or tracking information when available after an order has been prepared for shipment.

3. Shipping Carriers

Double Diamond Peptides LLC may ship orders using:

  • USPS
  • UPS
  • FedEx

The carrier and shipping service used for an order may depend on destination, package characteristics, service availability, cost, or other operational considerations.

Carrier availability may vary, and Double Diamond Peptides LLC reserves the right to select an appropriate carrier and service for fulfillment.

4. Shipping Charges

A flat-rate standard shipping charge of $11.95 applies to U.S. orders below the free-shipping threshold and is displayed during checkout before an order is submitted.

Orders with a qualifying merchandise subtotal of $250 or more are eligible for free standard shipping within the United States, unless otherwise stated at checkout.

Additional free standard shipping benefits may be available through Double Diamond Rewards, promotional offers, or other qualifying programs, subject to the applicable terms.

Taxes, discounts, promotional adjustments, or other charges may affect whether an order meets the applicable free-shipping threshold.

Any available expedited or alternative shipping options and their associated charges will be displayed at checkout when offered.

5. Backordered Products

Products identified as backordered are not subject to the standard 2–5 business day fulfillment estimate.

When an order contains both in-stock and backordered products, available in-stock products will be fulfilled without waiting for the backordered products.

Backordered products will ship separately when they become available.

Customers will not be required to delay shipment of available products solely because another product in the same order is backordered.

Material backorder delays may be communicated to the customer when appropriate.

6. Discreet Packaging

Orders are shipped in discreet external packaging.

External shipping packaging is designed to avoid unnecessarily identifying the specific products contained within the shipment.

Carrier-required shipping labels, return information, regulatory markings, or other information necessary for lawful shipment and delivery may still appear on the exterior of the package.

7. Shipping and Delivery Estimates

Shipping and delivery dates are estimates and are not guaranteed.

Once an order has been transferred to the carrier, delivery times may vary based on destination, carrier operations, weather, service interruptions, holidays, or other circumstances outside the reasonable control of Double Diamond Peptides LLC.

The processing and fulfillment period described in this policy is separate from the carrier’s transit and delivery time.

8. Shipping Addresses

Customers are responsible for providing a complete and accurate shipping address during checkout.

Please review your shipping information carefully before submitting an order.

Double Diamond Peptides LLC is not responsible for delays, failed deliveries, or other delivery problems caused by incorrect or incomplete shipping information supplied by the purchaser, except to the extent otherwise required by applicable law.

If you discover an address error after placing an order, contact us as promptly as possible. We may attempt to correct the address before fulfillment, but changes cannot be guaranteed once processing or shipment has begun.

9. Tracking

When tracking information is available, it may be provided by email, through the customer’s account where applicable, or through another order-status notification.

Tracking information is supplied by the carrier and may require time to update after a shipping label is created.

A tracking status indicating that a label has been created does not necessarily mean the carrier has physically received the package at that moment.

10. Lost, Damaged, or Delivery-Issue Shipments

If an order appears lost, arrives damaged, or presents another material delivery issue, please contact Double Diamond Peptides LLC promptly.

We may request information reasonably necessary to review the issue, such as:

  • Order number
  • Tracking information
  • Description of the problem
  • Photographs of the shipment, packaging, or product where applicable
  • Other information reasonably necessary to investigate the matter

When appropriate, Double Diamond Peptides LLC may assist with a carrier inquiry or provide another resolution consistent with our Refund and Returns Policy and applicable law.

11. Refused, Undeliverable, or Returned Shipments

If a shipment is refused, deemed undeliverable, or returned to sender, Double Diamond Peptides LLC may review the circumstances before determining whether reshipment or another resolution is available.

Additional shipping charges may apply when reshipment is requested due to an incorrect address, refusal, or another circumstance attributable to the purchaser, subject to applicable law.

12. Changes to This Shipping Policy

Double Diamond Peptides LLC may update this Shipping Policy from time to time to reflect changes in carriers, fulfillment practices, shipping services, business operations, or applicable requirements.

Changes become effective when the revised policy is posted to this website unless otherwise stated or required by applicable law.

The Last Updated date at the beginning of this page identifies the most recent revision.
