All orders are processed and shipped from our FDA-registered facility in the United States. Our fulfillment team operates Monday through Friday, excluding federal holidays.

Processing times may be extended during high-volume periods such as promotional events. You will be notified via email if any delay is expected.

We partner with USPS, UPS, and FedEx to offer reliable shipping options that suit your timeline and budget.

We ship to all 50 US states, including Alaska, Hawaii, Puerto Rico, and US territories. PO Boxes are accepted for USPS shipments only.

• Free shipping is automatically applied at checkout on all orders totalling $150 or more.
• Orders shipped to Alaska and Hawaii may require an additional 1–2 business days beyond the standard transit estimate.
• PO Box addresses must select USPS as the carrier; UPS and FedEx do not deliver to PO Boxes.
• All orders include a Certificate of Analysis (COA) in the shipment or accessible via your order confirmation email.
• Packages are shipped in plain, discreet packaging with no product labeling visible on the outside.

We currently ship internationally to select countries via USPS International Priority and DHL Express. International orders are subject to customs duties, taxes, and import fees which are the responsibility of the recipient.

We do not ship to countries where research peptides are explicitly prohibited by law. If your order is placed to a restricted country, it will be cancelled and refunded in full.

Once your order has been dispatched, you will receive an automated email containing your tracking number and carrier link. Here’s how the process works:

We take great care in packing every order. In the rare event that your order arrives damaged, broken, or contains incorrect items, please follow these steps:

• Do not discard any packaging, vials, or inserts — we may request photos for our quality claim.
• Photograph the outer packaging, inner contents, and any damaged or incorrect items clearly.
• Contact us at support@biotechpeptides.us within 72 hours of the delivery date.
• Include your order number and a brief description of the issue in your message.
• Our team will review and respond within 1–2 business days with a resolution — typically a free replacement shipment or full refund.

If your tracking shows “Delivered” but you have not received your package, please take the following steps before contacting us:

• Check around your property including porches, garages, and with neighbours.
• Check with other members of your household who may have accepted the delivery.
• Contact your local carrier facility directly with your tracking number — carriers can often locate misdelivered packages within 24 hours.
• Allow 2 business days after the delivery scan, as packages are occasionally marked delivered prematurely.

If the package is still not located after the above steps, contact us at support@biotechpeptides.us and we will open a formal carrier investigation. Lost package claims must be reported within 7 days of the marked delivery date.
