Free Shipping: Orders over $150 ship free inside the United States, 2-5 business days. No code needed. Standard International is free on orders of $500 and above.

International orders are dispatched on the same schedule as domestic orders, before 3 PM Central, seven days a week, and ship with tracking. Transit windows are estimates and do not include time held by the destination country. Duties and import charges, where they apply, are set by the destination country and are the recipient’s responsibility.

Both international rates are flat, so the price does not change with order size. Standard International is free on orders of $500 and above.

To Quito, Ecuador, for example, Standard International runs about 6 to 10 business days and Express International about 4 to 6 business days from the day the parcel leaves Austin.

All orders ship in plain, unmarked corrugated boxes. There is no external branding, product names, or company identification on the outer packaging. The packing slip inside includes your order details but contains no medical or product descriptions.

Compounds are packed with appropriate cold protection to maintain integrity during transit. Lyophilized peptides are stable at ambient temperature for short durations during shipping.

Card payments are charged at checkout and ship the same day, seven days a week, on orders placed before 3 PM Central. Bitcoin, Zelle, Cash App and Venmo are paid by hand after checkout: the discount comes off your total the moment you pick the method, the exact amount and the destination appear on the confirmation screen and in your order email, and the order ships the same day we confirm the payment. Bitcoin is on the Bitcoin network only. Questions go to info@coreresearchpeptides.com.
