Everything you need to know about how we ship orders, what happens if something goes wrong, and how to request a return or refund.
Orders are processed Monday through Friday, excluding federal holidays. Most orders are prepared and shipped within one (1) business day of confirmed payment.
Monday through Friday only. Orders placed after business hours, on weekends, or on holidays will be processed the following business day.
Processing begins only after payment is successfully authorized and confirmed. Pending or failed payments will delay fulfillment.
Some orders may be flagged for security review. If additional verification is required, we will contact you by email within 1 business day.
You will receive an order confirmation email immediately after payment, and a second email with your tracking number once your label is created.
Your tracking number is emailed as soon as your shipping label is created. Please allow up to 24 hours for the carrier to scan the package and for tracking to become active.
We ship all orders via trusted national carriers. Shipping method and cost are calculated at checkout based on your location and selected service level.
| Shipping Method | Estimated Delivery | Cost |
|---|---|---|
| Standard Shipping | 2–5 business days after shipment | Calculated at checkout |
| Express Shipping | 1–3 business days after shipment | Additional cost at checkout |
| Free Standard Shipping | 2–5 business days after shipment | FREE on orders over $150 |
Delivery time estimates begin from the date of shipment, not from the date of order placement. All estimated delivery times are provided by the carrier and are not guaranteed by Modern Peptide Labs.
We ship via USPS, UPS, and FedEx depending on your location and selected service. The specific carrier is determined at fulfillment. All shipments include tracking, and your tracking number will reflect the carrier assigned to your order.
Modern Peptide Labs is not responsible for delays caused by weather conditions, carrier disruptions, holidays, or peak shipping periods. Once your order leaves our facility, delivery timelines are in the carrier's hands.
Every order shipped by Modern Peptide Labs includes a tracking number. Here's what to expect:
Sent immediately after payment confirmation. Includes your order number and summary.
Sent when your label is created — typically within 1 business day. Includes your tracking number and carrier.
Allow up to 24 hours after label creation for the carrier to scan your package and activate tracking updates.
The carrier will mark your shipment as "Delivered" upon drop-off. If you have not received your package within 24 hours of a "Delivered" status, see the Shipping Issues section below.
If you haven't received your shipping confirmation email within 2 business days of your order, please check your spam folder first. If it's not there, contact us at support@modernpeptidelabs.com.
If your tracking shows "Delivered" but you have not received your package:
If the package cannot be located after 7 days from the expected delivery date, contact us at support@modernpeptidelabs.com and we will assist with the carrier claim. Reshipments are handled on a case-by-case basis following carrier confirmation.
Modern Peptide Labs is not responsible for packages that are confirmed delivered but subsequently stolen. We recommend requesting a signature-required delivery option or shipping to a secure location if theft is a concern in your area.
You are responsible for providing an accurate and complete shipping address at checkout. If you notice an error immediately after placing your order, contact us at support@modernpeptidelabs.com — we may be able to update the address if the order has not yet shipped.
Orders delivered to an incorrect address due to customer error are not eligible for a free replacement or refund. If the package is returned to us, additional shipping charges will apply for reshipment.
If your order arrives damaged or contains the wrong item, contact us within 48 hours of delivery at support@modernpeptidelabs.com. Please include:
We will resolve confirmed damage or incorrect shipment issues with a replacement or full refund at our discretion.
We offer a 30-day return policy on qualifying products. Returns must be initiated within 30 days of the original purchase date.
Opened or used products cannot be returned under any circumstances due to product integrity and research-use standards. Any indication of prior use will void return eligibility. Products returned without prior approval will not be accepted.
Send your return request to support@modernpeptidelabs.com with your order number, the product name, and your reason for return.
We will review your request and respond within 1–2 business days with either an approval and return instructions, or an explanation if the return does not qualify.
Once approved, send the product to our return address using a trackable shipping method. You are responsible for return shipping costs unless the return is due to our error.
After we receive and inspect the returned item, your refund will be processed within 2–5 business days to your original payment method.
Return Shipping: Customers are responsible for return shipping costs. We recommend using a trackable shipping service. Modern Peptide Labs is not responsible for returned items that are lost or damaged in transit back to us.
All approved refunds are issued to the original payment method used at checkout. We do not issue refunds via cash, check, store credit, or alternative payment methods.
Refunds are processed within 2–5 business days after your returned item is received and inspected. Your bank or payment provider may require additional time to post the credit to your account.
Refunds are credited to the original payment method only — credit card, debit card, ACH, or cryptocurrency wallet used at checkout.
You will receive an email confirmation once your refund has been processed on our end. If you do not see the credit within 5 business days, contact your payment provider.
Non-refundable payment processing fees may be deducted from your refund amount where permitted by applicable law.
Please contact us directly before initiating a chargeback or payment dispute. Unauthorized chargebacks may result in permanent account restriction and submission of transaction evidence to payment processors. We maintain full transaction records including delivery confirmation.
Due to our fast fulfillment process, order modifications and cancellations are only possible within a 30-minute window after placement.
In the rare event that a product becomes unavailable after your order is placed, we will contact you promptly and issue a full refund for the unavailable item. We do not substitute products without your consent.
For any questions about your order, shipping status, return requests, or refunds, please contact our support team. We respond within 24 hours, Monday through Friday.
