Shipping & returns policy

Orders are processed and shipped Monday–Friday (excluding U.S. federal holidays). You'll receive a tracking link by email as soon as your order ships.

Every order ships bubble-wrap protected in plain, discreet packaging — no product names or branding on the outside of the box. Lyophilized peptides are stable at room temperature during transit; cold shipping is not used or required.

Orders are fulfilled from within the United States and shipped via USPS. A tracking link is emailed as soon as your label is scanned so you can follow it to your door.

Because these are research materials, we cannot accept returns of opened or used product. If a product arrives with a documented quality or identity issue versus its Certificate of Analysis, contact us within 7 days and we will replace it or refund it.

If your order arrives damaged, email support@quantyxlabs.com with photos and your order number and we'll make it right. For orders marked delivered but not received, we'll help open a carrier trace.
