What We Can Help With

• Orders — order status, changes, or cancellations before fulfillment.
• Shipping — processing times, carrier information, tracking, and delivery issues.
• Returns — eligibility questions and starting a return under our Returns & Refunds policy.
• Account — login access, password resets, and updating account details.
• Documentation — locating a Certificate of Analysis, SDS, or specification sheet for a specific product and lot. Include the product name and lot number and our team will follow up directly.

What We Cannot Help With

Our support team does not provide medical, dosing, injection, administration, or treatment advice under any circumstances, for any product or purpose. All products are intended solely for qualified laboratory and research use. If your inquiry concerns how to use a product on a person or animal, we will be unable to respond to that portion of your request. See our Research-Use Policy for complete detail.

Before You Write

Having your order number and, where relevant, the lot number from your product label ready will help us resolve documentation and order questions faster.
