Shipping and Returns


We at Core Peptides offer Free Priority USPS shipping on orders over $100 within the US.

All our Free Shipping offers are for US addresses only, unless specified otherwise.

We offer same (business) day shipping for orders placed before 1pm PST Monday-Friday. All orders received after 1pm PST, or on weekends or holidays, will ship on the next business day.

We also offer Priority Express shipping (overnight USPS). We will soon be offering FedEx shipping as well. Stay tuned.

When your order ships, our systems will automatically generate a “Package Shipped” email notification that will include a tracking number.

Shipping rates and options, including free shipping, are subject to change at any time without notice.

Order Canceling and Returns

We have a straightforward cancellation and returns policy at Core Peptides.

If your order has not yet shipped, you may cancel your order by contacting us at for a refund, or get credit toward your next order, minus any payment processing fees.

Because these products are fragile and degrade over time if not properly handled and stored, we do not accept any returns after they have been shipped. Contact us in the rare case when you were to receive the wrong items, and our customer service staff will do their best to correct our error as soon as possible.

Bulk and Special Orders

Contact us for bulk or special orders. Our friendly customer service staff will work with you to satisfy any special requests.
