In-stock orders placed before 2:00 PM ET on a business day are dispatched the same business day; orders after cutoff or on weekends and holidays ship the next business day. You'll receive a confirmation email with tracking as soon as your order ships.

Domestic orders ship via FedEx with tracking. At checkout you can choose:

• FedEx Ground — 3–5 business days ($9, free over $200);
• FedEx 2-Day — 2 business days ($18);
• Standard Overnight — 1 business day ($38).

Every order ships in plain, unbranded, tamper-evident packaging. Nothing on the outside identifies the contents or Aureus Research. Products ship as a shelf-stable lyophilized powder and require no cold chain in transit.

Once an order is handed to the carrier, delivery is in their hands. We are not responsible for delays caused by the carrier, customs, weather, or other events beyond our control. If tracking hasn't updated in 24 hours, contact us and we'll open a trace.

Select international destinations are available at checkout. The buyer is the importer of record and is solely responsible for confirming that import of research compounds is lawful in their jurisdiction and for any duties or taxes that apply.

If your order arrives damaged, is incorrect, or is confirmed lost in transit, email support@aureus.shop with your order number within 14 days of the ship date and we'll make it right with a replacement or refund. Due to the nature of research materials, opened items cannot be returned.
