All sales are final after shipment

Due to product-integrity, contamination, storage, tampering, quality-control, and chain-of-custody concerns, all sales are final once an order has shipped. Products that leave our custody cannot be returned to saleable inventory.

We do not accept returns or exchanges for opened or unopened products after shipment, products ordered by mistake, products no longer wanted, carrier delays, address errors supplied by the customer, or products requested for any prohibited human, animal, veterinary, cosmetic, therapeutic, diagnostic, or medical purpose.

Cancellation before shipment

You may request cancellation before processing, packing, inventory allocation, payment verification, compliance review, or shipment begins. Cancellation is not guaranteed. We may deny a cancellation once fulfillment or review has started or where a manual payment has already been processed.

Damaged, missing, or incorrect orders

Contact us within 48 hours of carrier delivery confirmation for a shipment that arrived damaged, incomplete, or incorrect. Claims received later may be denied.

Your claim must include:

• Order number and tracking number.
• Clear photographs of the shipping box, shipping label, all packaging materials, every product label, and the reported condition.
• A written description identifying the affected item and issue.

Keep all packaging, labels, containers, inserts, and products until the claim is resolved. We may require carrier inspection or return of the affected material before considering a replacement, store credit, or refund.

Claim review

Submission does not guarantee approval. We may verify order records, shipping weight, package scans, inventory, photographs, communications, and carrier information. Remedies are determined based on the documented circumstances and applicable law.

Approved remedies

If we approve a claim, we may choose to replace the affected item, issue store credit, or issue a refund. Approved refunds may be returned to the original payment method or another lawful method we select. Bank and payment-platform processing times are outside our control. Original shipping charges, upgraded shipping, processing fees, return costs, and other nonrecoverable charges may be excluded except where prohibited by law.

Refused, abandoned, or undeliverable shipments

Orders refused, abandoned, unclaimed, returned because of an incomplete or incorrect address, or not retrieved from a carrier facility may be ineligible for replacement or refund. Any approved credit may be reduced by shipping, carrier, handling, processing, return, and restocking costs.

Research-use restriction

Any request or communication suggesting dosing, administration, ingestion, injection, topical application, treatment, human use, animal use, veterinary use, cosmetic use, or another prohibited purpose may be denied and may result in account restriction or refusal of future service.

No guarantee of research outcome

We do not guarantee suitability for a particular protocol, experimental result, analytical result, assay result, or research outcome. The purchaser is responsible for reviewing product specifications and available documentation and determining suitability for lawful laboratory use.

Payment disputes

Contact us first and provide a reasonable opportunity to investigate. Fraudulent claims, false statements, unauthorized reversals, or abusive chargebacks may result in order cancellation, account restriction, collection efforts, and preservation of relevant records. Nothing in this section limits non-waivable consumer rights.
