1. Inspecting your delivery
Inspect every shipment on arrival. Report damage, shortages or wrong items in writing within 2 business days of delivery, with your order number, lot numbers and photos of the packaging and vials.
2. All sales are final
We don't accept returns or exchanges, opened or unopened. If an order arrives damaged, short or incorrect, report it as described above and we'll make it right with a replacement or credit for the affected items.
3. Cancellations
You can cancel a quote at any time before it's accepted. Cancelling an accepted order requires our written agreement; orders that have shipped can't be cancelled.
4. Chargebacks & disputes
If something is wrong with an order, email [email protected] first. Every order is confirmed in writing, and we keep the order confirmation, research-use declaration, shipping and delivery records for each order.
Filing a chargeback on an order that was confirmed and delivered as described may lead to suspension of your account.
