Shipping & Returns

Orders placed before 2:00 PM ET on a business day are dispatched the same day. Orders placed after that, or on weekends and holidays, ship the next business day. You receive a tracking number by email as soon as the label is generated.

We ship domestically within the United States via FedEx. Standard delivery is typically 2 to 5 business days; expedited options are shown at checkout. Shipping is free on orders over $200; below that, live carrier rates are calculated at checkout.

We do not currently ship internationally. Delivery estimates are provided by the carrier and are not guaranteed.

Lyophilized material is stable at ambient temperature during transit and is shipped in discreet, unbranded outer packaging. On arrival, store vials as stated on the product page and certificate of analysis — typically refrigerated or frozen and protected from light.

Inspect your order on arrival. If a vial arrives broken, an item is missing, or the wrong product was sent, contact us within 7 days of delivery with your order number and photos of the packaging and contents. We will replace the affected items or refund them at our discretion, at no cost to you.

For packages marked delivered but not received, contact us within 14 days so we can open a carrier trace.

Because these are research chemicals whose storage conditions cannot be verified once they leave our facility, we cannot accept returns of opened, used, or otherwise released product. Unopened items may be returned within 14 days of delivery only with prior written authorization; approved returns may be subject to a restocking fee, and return shipping is the buyer’s responsibility.

Refunds are issued to the original payment method once the return is received and inspected. Any reward points earned on a refunded order are reversed.

We can change or cancel an order only before it is dispatched. Email us immediately with your order number; once a tracking number is issued, the shipment must be completed.
