Shipping Policy

Orders are processed Monday through Friday, excluding holidays. Orders placed before our daily cutoff of 2:00 PM (America/New_York) on a business day are dispatched the same day; orders placed after the cutoff, on weekends, or on holidays are dispatched the next business day.

The countdown shown on product and cart pages reflects the time remaining until that day's dispatch cutoff.

We currently ship only to the United States, Canada, and Mexico. Orders to any other destination cannot be placed, and the checkout will not accept an address outside these countries.

Certain compounds are additionally restricted from shipping to specific U.S. states for regulatory or carrier reasons. If an item in your cart cannot ship to your selected address, checkout will tell you which item is affected before payment.

Orders to Canada and Mexico ship with a customs declaration describing the contents as research materials for laboratory use only. Any import duties, taxes, or brokerage fees assessed by the destination country are the recipient's responsibility and are not included in our prices or shipping charge.

International transit and customs clearance may add time beyond the domestic delivery estimate.

We charge a flat shipping rate of $9.95 per order.

Shipping is free on orders of $150.00 or more (calculated on the order subtotal, before tax). Your cart shows the exact rate and remaining amount needed to qualify.

Orders ship via USPS. Estimated delivery is 2–5 business days after dispatch, depending on destination.

Delivery estimates are not guarantees; carrier delays outside our control may occur. All orders ship in plain, discreet packaging.

Higher-value orders ship with delivery-signature confirmation, so someone must be present to sign for the package.

A tracking number is added to your order once it ships and is visible in your account under Order History. Where the carrier provides a tracking link, it is included so you can follow the shipment.

You are responsible for providing a complete, accurate shipping address. We are not responsible for orders shipped to an incorrect address you or your authorized representative provided, or for shipments the carrier marks “delivered.” Packages returned to us as undeliverable may, at our discretion, be reshipped to a corrected address for an additional shipping charge. See our Returns & Refund Policy.

Title and risk of loss pass to you on delivery to the carrier. If tracking shows no movement or a shipment appears lost, contact support with your order number and we will open a carrier investigation and resolve it per our Returns & Refund Policy.
