Refunds and Returns

Our Shipping Policies

REAGENTS We ship chemical reagents worldwide Monday through Friday via UPS. If your order contains no chemical reagents, then it can be shipped through the US Postal Service (USPS), but if it contains chemical reagents, it has to be shipped UPS.

FENTANYL STRIPS We also ship fentanyl testing strips Monday through Friday. If you choose the free shipping option, we will send them first class mail in a small envelope with a stamp.

How long will your order take to get to you?

FENTANYL STRIPS WITH FREE SHIPPING Small orders of fentanyl strips with free shipping selected are sent in small, brown envelopes first class mail. They will arrive in your mailbox like a letter, not a package. The post office has been very slow these days to deliver first class letters, sometimes taking two weeks from the day we mail them. We have no control over this. If you need your fentanyl strips by a specific date, please choose a faster shipping method.

POSTERS WITH FREE SHIPPING We ship posters separately once a week via the US Postal service. They come in a tube. Fortunately, the post office appears to be delivering packages and tubes in a more timely manner than envelopes. They typically arrive within 3-5 business days after we drop them off.

REAGENTS AND EVERYTHING ELSE Orders placed before 11AM PST Mon-Fri are shipped the same day. Orders placed after 11AM PST ship the following business day. For domestic orders, UPS Ground is often the cheapest option. As a rule of thumb, UPS Ground can take up to eight days, especially if you live on the east coast. UPS 3-day select is guaranteed to arrive within three business days no matter where you live. Two Day Air will arrive within two business days. Next Day Air is guaranteed to arrive the next day. (So long as we receive the order by 11am PST.)

Do not Count Saturday!

UPS does not include weekend days in their shipping times. That means if you place an overnight order on Thursday afternoon or Friday before 11am PST, it won’t arrive until Monday. And if you place an overnight order Friday afternoon (or during the weekend), it won’t get shipped until Monday, and so it won’t arrive until Tuesday.

What about international orders?

If you choose UPS Worldwide Expedited Delivery, it will take approximately two business days to Canada, three to four days to Europe, and four to five days to Asia and Latin America.

For UPS standard international orders, please see the UPS website to calculate how long it will take.
