Orders placed before 2:00 PM CDT, Monday through Friday, are typically processed and shipped the same business day. Orders placed after the cutoff, on weekends, or on holidays will ship the next business day.

All orders are shipped via USPS Priority Mail or an equivalent carrier service. Standard delivery times within the U.S. typically range from 2-4 business days. Delivery estimates are not guaranteed and may vary based on carrier conditions.

Tracking information is automatically sent once your order has shipped. If you do not see your tracking email, please check your spam or promotions folder before contacting us.

Please make sure your shipping address is entered correctly at checkout. If you need to make a correction, contact us immediately at info@purebiolabs.com.

Once an order has been processed or shipped, we may not be able to make changes. We are not responsible for packages sent to an incorrect address entered by the customer at checkout.

Once a package is marked Delivered by the carrier, responsibility transfers to the customer. If your package is missing after being marked delivered, please contact your local USPS office or file a claim directly with the carrier.

We do not issue refunds or replacements for packages marked as delivered.

APO and military shipments may take 2-4 weeks depending on destination, customs, and carrier handling. Please allow additional time for these orders to arrive.

Shipping timelines may be affected during holidays, carrier closures, or severe weather. Any major shipping delays will be posted on our website when applicable.
