Shipping Policy

Where we ship

We ship to physical addresses in all 50 U.S. states from Phoenix, Arizona.

We do not ship internationally at this time, and we do not ship to freight forwarders. If you have address questions, contact support@psllabs.org before ordering.

Processing time

Orders usually pack and ship within 1 to 2 business days (Monday through Friday, excluding U.S. federal postal holidays) after payment clears.

Weekend and holiday orders enter the queue on the next business day.

Delivery timing

After the carrier accepts the package, standard domestic transit usually takes about 3 to 5 business days, depending on distance from Arizona.

Carrier timing is an estimate, not a guaranteed delivery date. Weather and carrier delays can change transit times.

Shipping rates

Standard domestic shipping is $9.99 on orders under $100.

Orders with a product subtotal of $100 or more get free standard U.S. shipping at checkout.

Packaging is chosen to protect vial seals and lyophilized material in normal transit.

Tracking

When your label is created, you get a shipping email with the tracking number.

You can also check status anytime on Track Order with your email and order number. Carrier scans can take up to 24 hours to appear after label creation.

Lost packages

If tracking shows no movement for more than 5 business days, or a package is marked delivered but you cannot find it, email support@psllabs.org with your order number.

We will open a carrier inquiry and explain next steps.

Damaged packages

If packaging or vials arrive damaged, report it promptly. Report order issues promptly after carrier-confirmed delivery. Include your order number and clear photos so we can review the claim. A fixed review deadline has not been published. Contact support@psllabs.org as soon as you notice a problem.

Photograph the outer box, label, packing materials, and damaged items. Email support@psllabs.org with your order number and photos.
