Shipping & Delivery

Fast Shipping Is Included

Every Celtek Peptides order includes 2nd Day Air shipping at no additional charge. Pleas supply a street address, no PO Boxes, as our 2nd day carriers such as UPS and Fedex will not deliver to PO Boxes.

There is no separate standard-shipping fee added at checkout. The price you see for the product already includes expedited 2nd Day Air delivery.

Need your research materials sooner? Next Day Air shipping is also available for an additional charge.

Our shipping options are simple:

Shipping MethodCostTypical Transit
2nd Day AirIncluded in product price2 business days after shipment
Next Day AirAdditional chargeNext business day after shipment

Transit time begins once the order has been processed and transferred to the carrier.

2nd Day Air Shipping Included With Every Order

We do not use slow economy shipping as the default option for Celtek peptide orders.

Instead, orders ship using 2nd Day Air service as our standard shipping method.

The cost is already built into our product pricing.

That means researchers do not need to choose between paying extra for reasonable delivery times or waiting through a longer economy-shipping window.

When you order from Celtek Peptides:

2nd Day Air shipping is included.

There is no additional charge for this standard expedited shipping option.

Need It Faster? Choose Next Day Air

For time-sensitive research projects, Next Day Air shipping is available for an additional charge.

Next Day Air is the fastest shipping option currently offered by Celtek and is designed for orders where minimizing transit time is important.

The additional cost depends on the shipment and will be shown or communicated as part of the order process.

Keep in mind that expedited shipping affects carrier transit time, not necessarily the amount of time required to prepare or process an order before shipment.

Shipping Time vs. Processing Time

Shipping time and processing time are two different things.

Processing time is the period between placing an order and Celtek releasing the package to the carrier.

Transit time begins after the carrier receives the package.

For example, 2nd Day Air generally means the package is scheduled for delivery on the second applicable business day after it enters the carrier’s network.

Choosing Next Day Air reduces the transportation portion of the order timeline, but it does not make an order that has not yet been processed instantly ready to ship.

This distinction becomes especially important when ordering:

  • custom synthesized peptides
  • products requiring additional documentation
  • large orders
  • special-request materials
  • items that are not currently ready for shipment.

If your project has a firm deadline, contact Celtek before ordering so we can confirm the applicable timeline.

Why Celtek Uses Expedited Shipping

Research materials should not spend unnecessary time moving through the shipping network.

Using 2nd Day Air as our standard shipping method reduces the amount of time products spend in transit compared with conventional ground or economy shipping.

It also creates a more predictable shipping experience for research customers.

Instead of offering a low advertised product price and then adding expedited shipping at checkout, Celtek includes the cost of 2nd Day Air directly in the product price.

We think that is simpler.

How Shipping Pricing Works

For standard orders:

Product price + included 2nd Day Air shipping = your standard shipping arrangement.

You are not required to purchase an expedited upgrade to receive 2nd Day service.

If you select Next Day Air, only the additional cost associated with the faster shipping service is added.

This makes it easier to understand the actual delivered cost of an order before reaching checkout.

Order Packaging

Celtek packages research materials to protect the product and associated documentation during shipment.

Packages are prepared with attention to:

  • product identification
  • lot traceability
  • protection during transit
  • order accuracy
  • accompanying documentation where applicable.

The product label and lot number should be retained after delivery because the lot number connects the material to its applicable analytical testing and Certificate of Analysis.

You can locate available reports through our Testing & Certificates of Analysis page.

Check Your Shipment When It Arrives

Researchers should inspect orders promptly after delivery.

Check that:

  • the correct products were received
  • quantities match the order
  • containers are intact
  • labels are readable
  • lot numbers are present
  • any expected documentation is included or available online.

If something appears incorrect or damaged, contact Celtek as soon as possible and retain the packaging and product information.

Providing the order number, peptide name, and lot number will help us identify the shipment.

What If My Package Is Delayed?

2nd Day Air and Next Day Air are expedited carrier services, but carrier transit can occasionally be affected by circumstances outside Celtek’s control.

Possible disruptions can include:

  • severe weather
  • transportation interruptions
  • carrier network delays
  • holidays
  • incorrect or incomplete delivery information.

A shipping service level describes the expected carrier transit time. It does not eliminate every possibility of a delay.

If a shipment appears to have an issue in transit, contact Celtek so the shipment can be reviewed.

Business Days and Holidays

Expedited shipping schedules are generally based on business days.

Weekends and holidays may affect both pickup and delivery dates.

For example, a package entering the carrier network late in the week may follow a different delivery schedule than one shipped earlier in the week.

If your research schedule depends on receiving an order by a specific date, contact Celtek before ordering.

Next Day Air Does Not Mean Same-Day Delivery

Next Day Air means delivery is expected on the applicable business day following shipment under the carrier’s service terms.

It does not mean the product will arrive on the same day the order is placed.

Order processing must occur before the carrier transit period begins.

This is an important distinction when planning a time-sensitive research project.

Custom Peptide Synthesis Shipping

Custom peptide synthesis projects follow a different timeline from products that are already available for shipment.

The synthesis process itself may require time for:

  • peptide synthesis
  • purification
  • analytical testing
  • documentation
  • preparation for shipment.

Once the completed project is ready to ship, the applicable expedited shipping service can then begin.

Researchers should therefore treat the quoted custom synthesis turnaround time separately from carrier transit time.

Learn more on our Custom Peptide Synthesis page.

Analytical Documentation and Your Shipment

Where applicable, Celtek products are associated with lot-specific analytical documentation.

Researchers should compare the lot number received with the applicable test report.

The relationship should be:

Product → Lot Number → Analytical Report

This allows the researcher to identify the testing associated with the particular batch received rather than relying on a generic test report for the compound.

Does 2nd Day Air mean my order arrives two days after I place it?

Not necessarily.

2nd Day Air refers to the carrier transit period after shipment. Any applicable order processing occurs before that transit period begins.

Does Next Day Air mean my order ships immediately?

No. Next Day Air shortens carrier transit time after the package ships. It does not eliminate any processing required before the package is ready for the carrier.

What if I have a strict delivery deadline?

Contact Celtek before placing the order. We can help clarify the expected processing and shipping timeline so you can determine whether it fits your research schedule.

Is expedited shipping an additional fee?

Standard 2nd Day Air is already included in Celtek product pricing.

Only the optional Next Day Air upgrade carries an additional shipping charge.

What should I do when my package arrives?

Inspect the package and confirm the products, quantities, labels, and lot numbers. If there is a problem, retain the packaging and contact Celtek with your order information.
