Dispatch & cut-off
All orders are packed and handed to the carrier from our facility in Delaware. The daily cut-off is 2:00pm Eastern Time, Monday through Friday. An order confirmed before the cut-off on a business day leaves the same afternoon; an order confirmed after 2pm, or at any time on a weekend or U.S. federal holiday, leaves on the next business day.
"Confirmed" means payment has cleared and no compliance hold is in place. Crypto payments are confirmed once the network shows the required number of confirmations, which can take longer than a card payment, so allow for that if you are aiming for same-day dispatch.
The catalog and cart show a live "ships today" or "ships tomorrow" indicator based on the current Eastern time, so you always know which side of the cut-off you are on before you pay.
Carriers & transit
Our standard domestic service is UPS 2nd Day Air®. Because we dispatch same day, most U.S. addresses receive their order two business days after it leaves Delaware. An overnight option (UPS Next Day Air®) can be selected at checkout for time-critical work; the extra cost is shown before you confirm.
Transit days are business days. A package dispatched on Thursday by 2nd Day Air is scheduled for Monday, not Saturday, unless you have chosen a Saturday delivery upgrade where UPS offers one.
Tracking
A tracking number is emailed to the address on your account as soon as the label is scanned by the carrier, normally the same evening. Your order history also links to live tracking for every shipment.
Delivery estimate
Enter your ZIP code in the cart and the catalog will show an estimated arrival date for each product. The estimate is calculated from the cut-off, the carrier's published transit time for your ZIP and the current day of the week. It is an estimate, not a guarantee; weather, carrier volume and address problems can add time.
Packaging & temperature
Our peptides are supplied as lyophilised (freeze-dried) powder in sealed glass vials. In this form they are stable at ambient temperature for the length of a normal transit, so they ship without dry ice. Each order is packed in an insulated mailer inside a rigid outer box with cushioning around every vial.
During the warmer months (typically May through September, or whenever the forecast along the route exceeds 85°F) we add a frozen gel pack to keep the contents cool in transit. The gel pack may have thawed by the time the box arrives; that is expected and does not affect the material.
Store vials at 2–8°C on arrival and keep them out of direct light. Reconstituted solutions should be handled according to your laboratory's own protocols.
What is in the box
- Each vial, individually labelled with the product name, quantity and batch number.
- A printed certificate of analysis for every batch in the order, showing 99%+ purity verified by Meridian Analytical Labs, an independent laboratory.
- A packing slip listing the contents and your order number.
- Discreet outer packaging with no product description on the label.
Certificates can also be downloaded at any time from the certificate library, and any batch number can be checked with batch lookup.
Rates & free shipping
Domestic shipping is priced simply: a flat $20 for UPS 2nd Day Air on any order, and free once the merchandise subtotal reaches $250. The threshold is calculated on product value only, before any tax and after discounts.
The cart shows how far you are from free shipping as you add items. Shipping charges are never refunded for delays caused by the carrier, but we will refund them in full if a delay is our fault (for example, a missed dispatch day).
Address accuracy & changes
You are responsible for the shipping address you enter. Please check unit numbers, ZIP codes and the recipient name before confirming; carriers will not deliver to an incomplete address and we cannot alter a label once the package has been scanned.
Changing an address
If you spot a mistake, email research@aminostation.com with your order number as soon as possible. Changes requested before the 2pm ET cut-off on the dispatch day are made free of charge. After the package has left, any redirection depends on the carrier and is billed at the carrier's intercept fee.
Undeliverable packages
A package that is refused, returned as undeliverable or held because of an address error will be reshipped once it is back with us, at your cost for the second shipment. If you prefer not to reship, we refund the product value less the original shipping charge once the package is returned and inspected.
We ship to residential, institutional and business addresses. We do not ship to freight forwarders or mail-drop services without prior approval, and we do not ship to P.O. boxes because UPS cannot deliver to them.
Lost, delayed or damaged shipments
Risk of loss passes to you when the carrier accepts the package, but in practice we deal with the carrier so you do not have to.
Damaged on arrival
Photograph the outer box, the inner packaging and the affected vials before discarding anything, and send the photos with your order number. Do not use a vial whose seal is broken.
Marked delivered but not received
Check with neighbours, a mailroom or reception first; carriers sometimes scan a package a few hours before it is physically dropped off. If it has not turned up within one business day of the scan, contact us.
What we do
- We file and follow up the claim with UPS ourselves.
- Once the loss or damage is confirmed, or within five business days if the carrier has not responded, we send a replacement from the same or a comparable batch at no charge.
- If you would rather not wait, or the item is out of stock, we issue store credit or a refund to the original payment method instead.
Delays that are not losses (weather, carrier backlogs) are outside our control. We will chase the carrier and keep you updated, but a delay by itself does not qualify for a replacement unless the contents are compromised.
International orders
We ship to a limited list of countries outside the United States. Availability for your destination is shown at checkout; if a country is not listed, we cannot ship there.
For any delivery outside the U.S., you are the importer of record. That means you are responsible for:
- confirming that the materials can lawfully be imported for research purposes at your destination;
- any import permit, licence or institutional paperwork your customs authority requires;
- duties, VAT, brokerage and any other charge assessed on import, which are collected by the carrier and are not included in our shipping price.
International shipments travel by UPS Worldwide Express or Expedited and normally clear customs within one to five business days. Packages that are seized, refused or destroyed by customs, or returned because required paperwork was not supplied, are not eligible for a refund of product or shipping.
Restricted destinations
We do not ship to countries subject to U.S. sanctions or export restrictions, or to destinations where the materials are classified as controlled substances. This list changes; if a destination becomes restricted after you have ordered, we cancel and refund the order in full.
Returns
Because our products are research chemicals whose chain of custody cannot be verified once they leave our facility, we cannot accept returns of shipped materials. This protects every researcher who orders from the same batch. The only exception is our own error: if you receive the wrong product, the wrong quantity or an item you did not order, contact us and we will collect it at our expense and send the correct item or a refund.
Orders can be cancelled for a full refund at any time before they have been dispatched. Once a label has been scanned, the shipment is treated as delivered for the purposes of this section.
Concerns about quality
If you have reason to doubt the purity or identity of a vial, the answer is testing rather than a return. Under our retest guarantee you can send a sample to an independent laboratory of your choice; if the result falls short of the certificate we shipped, we refund the cost of that testing as store credit and replace the material. Full details, including how to submit results, are on the retesting page.
