Shipping Policy

Last updated: August 10, 2026. This policy describes exactly what is charged at checkout. If anything on this page ever disagrees with the total you see at checkout, the checkout total is what applies — and we would like to know about it.

Processing Time

Orders are prepared and dispatched within 1–2 business days. Orders placed before 2:00 PM ET on a business day typically ship the same day. We do not process or dispatch on weekends or US public holidays.

If an item is running low on stock, the product page will say so and the order may take an additional 5–7 days to leave our facility.

Domestic Shipping (United States)

Standard shipping is free on every order. There is no minimum. Typical transit time is 3–5 business days after dispatch.

Next Day Air is available for $15.00, United States only. Next-day delivery runs Monday to Friday and requires the order to be placed by 2:00 PM ET on a business day. Orders placed after the cutoff, on a weekend or on a holiday enter the next business day’s dispatch.

Canada

Standard shipping to Canada is free, with no minimum. Transit times vary by destination and customs processing. Any import duties or taxes charged on arrival are the responsibility of the recipient.

International Shipping

A flat rate of $48.00 applies to international orders outside the United States and Canada. Typical transit time is 7–14 business days, and customs clearance can extend that.

Import duties, taxes and customs fees are set by the destination country and are the responsibility of the recipient. They are not included in the shipping rate and we cannot estimate them in advance.

We ship only to destinations available in the country selector at checkout. If your country is not listed, we are not able to accept the order.

Brazil

For orders to Brazil the shipping rate is included and the applicable customs charge is calculated and displayed at checkout, so the total shown is the total due.

Tracking

A tracking number is issued once the order is dispatched and is sent to the email address on the order. Tracking can also be viewed from your account, under the order. It is normal for a tracking number to take up to 24 hours to start showing scans after it is issued.

Temperature-Sensitive Products

Temperature-sensitive items ship with cold chain packaging appropriate to the compound and the destination. Lyophilized peptides are stable at ambient temperature for the duration of normal transit; they should be moved to the storage condition printed on the vial as soon as they arrive.

Delivery Address

Orders ship to the address entered at checkout. Please check it before completing the order — we cannot change an address once the order has been dispatched. If a package is returned to us as undeliverable because of an incorrect or incomplete address, we will contact you to arrange reshipment; reshipment costs may apply.

Lost or Undelivered Packages

If tracking shows no movement or the package has not arrived, contact us within 30 days of the expected delivery date. We will open an investigation with the carrier. Once the carrier confirms the package is lost, we will reship the order or issue a full refund, whichever you prefer.

Damaged or Incorrect Items

If an order arrives damaged, defective or incorrect, contact us within 7 days of delivery with photographs of the item and its packaging. This is covered by our Return & Refund Policy, which also covers returns of unopened product within 30 days.

Research Use Only

All products are supplied for laboratory research and in-vitro experimental use. They are not for human or veterinary use. Placing an order confirms that the products will be handled by qualified personnel in an appropriate setting.
