Last updated: July 8, 2026Quality 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.
Expected delivery within 2–4 business days after dispatch within the contiguous United States. Carrier scans and rural routes may add a day in isolated cases.
Complimentary on all orders; a faster option is available below.
Faster service for time-sensitive lab schedules. Next-day or 2-day delivery depending on your location, when ordered before the daily cutoff.
Final delivery date is estimated by the carrier once labeled. Orders placed after the cutoff ship the next business day.
- Orders placed before 4:00 PM Eastern Time (ET), 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.
Vayron Labs does not accept returns, issue refunds, or allow order cancellations once an order has been placed, regardless of delivery status.
Once a shipment is marked as "Delivered" by the carrier, responsibility for the package transfers to the customer.
Vayron Labs 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.
In the event of a verified Vayron Labs fulfillment or shipping error, such as incorrect items, missing items, or damage incurred during transit prior to delivery, customers must notify us 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.

Chargebacks submitted for delivered, refused, or stolen packages will be disputed using carrier confirmation, delivery records, and the customer's agreement to these terms.
