Shipping Policy

All orders are processed within 1-2 business days (Monday through Friday, excluding holidays). Orders placed after 2:00 PM ET or on weekends and holidays will be processed the next business day. You will receive a confirmation email with tracking information once your order has shipped.

We offer the following shipping options for orders within the United States and Canada:

All domestic orders are shipped via USPS or UPS. Delivery times are estimates and are not guaranteed. Orders placed before 2:00 PM ET typically dispatch the same business day.

We currently ship to the United States and Canada. Canadian orders typically take 5-10 business days for delivery, depending on the destination and customs processing.

International customers are responsible for any customs duties, taxes, or import fees imposed by their country. One Plus is not responsible for delays caused by customs clearance.

Once your order has shipped, you will receive an email with a carrier tracking number. You can use this number to track your package through the carrier’s website. Your order reference (ONE-XXXXXX) is included in every confirmation email.

Please allow up to 24 hours for tracking information to become active after receiving your shipping confirmation.

We currently ship to all 50 US states and Canada. Certain products may have shipping restrictions based on local or state regulations. If your order contains a restricted item, we will contact you to discuss alternatives or issue a refund for the affected product.

All products are sold strictly for laboratory research use only. Orders may be refused or cancelled if shipping restrictions apply to the destination address.

One Plus is not responsible for packages that are lost, stolen, or damaged after they have been handed off to the shipping carrier. If your tracking shows the package was delivered but you did not receive it, please contact the carrier directly.

For packages confirmed as lost in transit, please contact us at support@onepluslabs.com and we will work with you to resolve the issue.

Please ensure your shipping address is accurate and complete when placing your order. We are not responsible for orders shipped to incorrect addresses provided by the customer.

If a package is returned to us due to an incorrect address, we will contact you to arrange reshipment at your expense.

Lyophilized peptides are stable at room temperature during transit. During warmer months, we may use insulated packaging or cold packs to maintain product integrity during transit at no additional cost.
