Shipping Policy

1. Where We Ship

PYXAX ships to addresses within the United States only. We do not ship internationally, and we do not accept orders with a non-US billing or shipping address. Checkout will not accept an address outside the United States, and we cannot arrange freight forwarding, third-party export, or delivery to a foreign address through an intermediary.

2. Order Processing

Orders are processed within 1 business day of payment clearing. Orders placed on weekends or US public holidays are processed on the next business day. Processing time is separate from transit time — the delivery estimates below begin when the carrier receives the package, not when the order is placed.

An order may be held beyond this window if the researcher confirmation or research-purpose information supplied at checkout requires clarification. We will contact you at the email address on the order if that happens.

3. Delivery Options and Transit Times

All transit times are estimates in business days, exclude weekends and US public holidays, and begin at carrier handoff. Rates are calculated at checkout.

• Standard Shipping — 3–5 business days. $12.99.
• Priority Shipping — 2–3 business days. $14.99.
• Overnight Shipping — 1 business day. $49.99.
• Free Priority Shipping — 2–3 business days, applied automatically on orders of $250.00 or more (order subtotal, before shipping and any applicable tax), or where a valid free-shipping promotion is applied.

Delivery estimates are provided by the carrier and are not guaranteed. Weather, carrier backlog, and address correction can extend transit beyond the estimate.

4. Tracking

Every order ships fully tracked. A tracking number is emailed to the address on the order at fulfillment, and is also available under Orders in your account. If you have not received tracking within 2 business days of your order confirmation, contact hello@pyxax.com with your order number.

5. Carrier Terms and Risk of Loss

PYXAX selects the carrier for each order. Once an order is handed to the carrier and tracking is provided, the shipment is subject to that carrier’s terms of service, and responsibility for the package transfers to the carrier. PYXAX is not responsible for packages that are lost, stolen, delayed, or misdelivered after carrier handoff, though we will assist with filing a carrier claim where one is available.

Delivery to the address supplied at checkout completes our obligation. We cannot reroute, intercept, or recall a package once it has shipped. An address entered incorrectly at checkout may result in a carrier address-correction fee, a delayed delivery, or a returned package; returned packages are handled under our Refund & Cancellation Policy.

6. Handling and Storage on Arrival

Compounds ship as lyophilized powder, which is stable at ambient temperature for the duration of domestic transit. On receipt, store each compound as stated on its product page and on the accompanying documentation. PYXAX is not responsible for material degraded by storage or handling after delivery.

7. Damaged, Incorrect, or Missing Orders

Inspect your order on arrival. Claims for damaged or incorrect shipments must be submitted within 48 hours of delivery, with your order number, a description, and clear photographs of the product and packaging, under our Refund & Cancellation Policy. Contact hello@pyxax.com.
