Same-Day Dispatch
Orders confirmed by 12pm EST are dispatched the same business day, Monday to Friday.
Cold-Chain Packaging
All peptide orders are packed with thermal insulation and ice packs at no additional cost.
Discreet Outer Packaging
Plain, unmarked outer packaging. No product names, branding, or company information on the exterior.
Order Processing
Orders are processed Monday through Friday, excluding US federal holidays. Payment must be confirmed before processing begins. Orders confirmed by 12pm EST are dispatched the same business day; orders received after 12pm EST are dispatched the following business day.
You will receive an order confirmation email immediately after purchase. A dispatch notification with your tracking number is sent once your order has been collected by the carrier, typically before 5pm EST on the dispatch day.
Orders placed over weekends or on US federal holidays are queued for dispatch on the next available business day. During exceptionally high-demand periods, dispatch may be delayed by one additional business day. We will notify you by email if this applies to your order.
Please note: Dispatch and delivery are separate events. An overnight service (such as UPS Next Day Air) refers to the transit time from dispatch, not from the time of ordering. If you order on a Friday after 12pm EST, dispatch will occur on Monday, with delivery Tuesday.

Cold-Chain Packaging
All peptide orders are shipped with thermal insulation and ice packs as standard, at no additional charge. Our cold-chain packaging is designed to maintain internal temperatures within the recommended storage range for a minimum of 48 hours under typical US transit conditions.
Vials are individually wrapped in protective foam or bubble wrap and placed inside a rigid inner box before being packed into the thermal outer layer. This protects against both temperature excursion and mechanical damage during transit.
Upon receipt, lyophilised peptides should be transferred to a refrigerator (2 to 8 degrees Celsius) or freezer (minus 20 degrees Celsius) promptly, depending on the compound and your intended storage period. Refer to the product-specific COA for storage recommendations.
Inner packaging
Protective foam or bubble wrap around each vial
Thermal layer
Insulated liner rated for 48+ hours transit
Outer packaging
Plain, unmarked — no product names or branding
International Shipping
We ship to select countries via USPS Priority Mail International.
Important: It is the buyer's sole responsibility to confirm that research peptides are legal to import in their country or jurisdiction before placing an order. Pure Peptides accepts no liability for orders held, seized, or refused by customs authorities. We do not falsify customs declarations or undervalue shipments.
| Region | Estimated Delivery | Service |
|---|---|---|
| Canada | 5 to 10 business days | USPS Priority Mail International |
| Western Europe | 7 to 14 business days | USPS Priority Mail International |
| Australia / New Zealand | 10 to 20 business days | USPS Priority Mail International |
| Rest of World | 10 to 21 business days | USPS Priority Mail International |
International delivery estimates begin from the date of dispatch and do not include time spent in customs processing. Customs delays are outside our control and can add several days to estimated arrival times, particularly for first-time imports or during peak periods.
International orders may be subject to import duties, customs fees, or handling charges levied by the destination country. These charges are the responsibility of the recipient and are not included in our shipping fees. We recommend checking your country's import thresholds before ordering.
We do not ship to countries where research peptides are explicitly restricted or require an import licence. If you are unsure whether we deliver to your country, contact us before placing an order.
Tracking Your Order
All services include end-to-end tracking. Track your shipment at usps.com or ups.com using the tracking number included in your dispatch confirmation email.
Tracking events typically update within a few hours of the parcel being scanned at a carrier facility. The first scan may not appear until the parcel has been collected and processed, which can be several hours after dispatch.
All orders are shipped with a tracked service. If you have not received your tracking number within 24 hours of your dispatch confirmation, please contact us.
All tracked services include
- Scan at collection and each transfer point
- Attempted delivery scan
- Delivery confirmation with time stamp
- Email notifications from carrier
UPS Next Day Air additionally includes
- Signature required on delivery

- Eligible for UPS money-back guarantee if late

Lost or Damaged Shipments
If your order arrives damaged, contact us within 48 hours of delivery with your order number and photographs of the outer packaging and affected items. We will file a claim with the carrier and arrange a replacement or refund once the claim is assessed.
If your tracked order has not arrived within the estimated transit window, contact us and we will open an investigation with the carrier. USPS considers a Priority Mail package lost after 15 days from the date of mailing; UPS typically requires 8 business days before opening a lost claim. We cannot dispatch a replacement or issue a refund until the carrier has concluded their investigation.
If tracking shows "Delivered" but you have not received your package, check with neighbors and any safe locations around your property. If the package cannot be located, contact us within 5 days of the delivery scan. The carrier may require a signed declaration from you before processing a claim.

Shipping FAQs
Can I upgrade my shipping after placing an order?
Shipping upgrades are possible only if the order has not yet been dispatched. Contact us immediately via the contact page with your order number and preferred service. Once a dispatch confirmation has been sent, we cannot change the shipping method.
Do you offer free shipping?
We do not currently offer free shipping thresholds. Shipping is calculated at checkout based on your selected service. All orders include cold-chain packaging at no extra charge regardless of shipping tier.
How do I track my order?
All orders include a tracking number sent via email once dispatched. You can track your shipment at usps.com or ups.com depending on the service selected at checkout.
Do you ship to PO Boxes?
USPS Priority Mail can deliver to PO Box addresses. UPS services require a physical street address and cannot deliver to PO Boxes.
Do you ship to APO/FPO military addresses?
Yes. We ship to APO/FPO addresses via USPS. Delivery times to military addresses vary and are outside our control.
What if nobody is home to receive my package?
UPS will make up to 3 delivery attempts and may leave the package in a safe location or hold it at a UPS Access Point. USPS will leave packages at the door or hold them at your local post office. You can reschedule delivery via usps.com or ups.com.
