US warehouse 01 and US warehouse 02
Each warehouse serves United States addresses only, dispatches within 24 hours and has estimated standard delivery of 3–5 days. Current standard and overnight shipping rates and dispatch policies are shown in each warehouse’s catalog and above. Checkout confirms destination coverage and the final charges. Both warehouses sell kits of 10 vials; their catalogs, prices and shipments are independent.
Free shipping per warehouse
Standard shipping is free once the selected merchandise from a single warehouse reaches that warehouse’s minimum, shown above. The threshold uses merchandise before discounts, excluding gifts, shipping and tax. Each physical warehouse has a separate minimum; their totals do not combine. Expedited services have separate charges.
Multiple warehouses and packages
Each warehouse is charged separately and may send multiple packages. Review each warehouse’s delivery service and charge at checkout. Your order shows quantities, batches and tracking details for each package.
