Delivered with Care

Shipping & Returns

How we process, package, and ship your order — plus our policy on returns, replacements, and damaged or incorrect items.

Last updated: June 21, 2026

Quality You Can Trust

Every order is carefully prepared, inspected, and shipped with the utmost care. We stand behind the quality and purity of every product we deliver.

Shipping Options

At checkout you may choose one of the following methods. Rates and transit times below match what you see in your cart.

Free USPS Priority Shipping - $0

Typical delivery: 2-3 business days after dispatch within the contiguous United States. Carrier scans and rural routes may add a day in isolated cases.

Default option for research peptide orders—no minimum purchase required for this complimentary service.

USPS Next-Day Express - $35

Expedited service for time-sensitive lab schedules. Most destinations: 1-2 business days after dispatch, depending on ZIP code and carrier operational timelines (checkout mirrors this language).

Express is optional; availability of overnight status varies by location. Final delivery date is estimated by the carrier once labeled.

Orders placed before 4:00 PM Eastern Time (EST), Monday through Friday, typically ship the same business day.
Orders placed after the cutoff, on weekends, or on U.S. federal holidays are processed on the next business day.
You will receive an email confirmation when your order is received and another when it ships with tracking details.

Refunds & Returns

Due to the sensitive nature of our products and applicable regulatory requirements, all sales are final.

Ascend Science does not accept returns, issue refunds, or allow order cancellations once an order has been placed, regardless of delivery status.

Delivered Packages

Once a shipment is marked as “Delivered” by the carrier, responsibility for the package transfers to the customer.

Ascend Science is not responsible for packages that are lost or stolen after delivery, including theft from porches, mailrooms, front desks, lockers, or other delivery locations.

Refunds, credits, or replacements will not be issued for packages confirmed as delivered by the carrier.

Shipping Damage or Fulfillment Errors

In the event of a verified Ascend Science fulfillment or shipping error, such as incorrect items, missing items, or damage incurred during transit prior to delivery, customers must notify Ascend Science within seven (7) calendar days of the carrier's delivery date.

This reporting window is firm. Requests submitted outside of this timeframe will be denied without exception.
