All sales are final. Because of the nature of research materials, we cannot accept returns, refunds, or exchanges.
Last updated: June 24, 2026
To protect the integrity and safety of our research materials, we cannot accept the return of any product once it has left our facility, and we cannot resell returned items. Please order carefully.
Once a product leaves our control, we cannot verify the conditions under which it was stored or handled. To guarantee the purity, identity, and safety of everything we ship to other researchers, returned items cannot be re-inspected or re-sold. For this reason all sales are final, and we do not offer returns, refunds, exchanges, or store credit for change of mind, ordering errors, or unwanted items.
We stand behind what we ship. If your order arrives damaged, or you received the wrong item, contact us within 7 days of the delivery date with your order reference and clear photos of the product, packaging, and shipping label. If we confirm the issue, we will, at our discretion, send a replacement or issue a refund for the affected item(s). This is the only circumstance under which a refund or replacement is provided.
Packages lost in transit are handled under our Shipping Policy. Report a non-moving or missing shipment within 7 days so we can open a carrier investigation.
Orders may be cancelled only before they have been dispatched. Once an order has shipped, it cannot be cancelled and all sales are final.
Reach us through our contact page within the 7-day window above, include your order reference and photos, and we'll make it right where the conditions above are met.
