Shipping Policy
Processing time
Orders placed before 2:00pm ET on a business day ship the same day. Orders placed after 2:00pm ET, on weekends, or on federal holidays ship the next business day.
During new batch releases or promotional periods, processing may extend to 1–2 business days. If your order will be delayed beyond that, we email you before it ships.
Shipping rates
| Order value | Rate |
| Under $200 | $X.XX flat rate |
| $200 and over | Free |
Rates are calculated at checkout. Expedited options, where available, are shown at checkout with their own pricing.
Carriers and transit time
We ship via USPS / UPS / FedEx. Typical domestic transit is 2–5 business days after dispatch, depending on destination and service level.
Transit time is separate from processing time. A same-day dispatch is not a same-day delivery.
Tracking
A tracking number is emailed as soon as your label is generated. Tracking can take up to 24 hours to show movement after the label is created — this is normal and does not mean the package is lost.
Packaging and cold chain
Lyophilized vials are stable at ambient temperature in transit. Orders are cold-packed / packed with an insulating liner and sealed for protection against light and handling damage.
If your order arrives with the cold pack thawed, the product is not compromised — lyophilized material does not require refrigeration in transit. Storage guidance for each compound is on its product page.
Delivery protection
Every order ships with delivery protection at no additional cost. Packages that are lost in transit, damaged on arrival, or marked delivered but not received are replaced at no charge.
To file a claim, email support@nuflowlabs.com with your order number within 30 days of the ship date. For damage claims, include photos of the outer packaging and the vials as received.
Address accuracy
We ship to the address entered at checkout. We cannot reroute a package after a label is generated.
If a package is returned to us as undeliverable due to an incorrect or incomplete address, we will reship once the address is corrected, with reshipment postage charged to the customer. Delivery protection does not cover address errors.
International shipping
We currently ship within the United States only.
We ship to LIST OF COUNTRIES. International customers are the importer of record and are solely responsible for any duties, taxes, brokerage fees, and compliance with the import laws of their destination country. We cannot advise on whether a given compound may be lawfully imported into your jurisdiction. Packages seized, refused, or destroyed by customs are not covered by delivery protection and are not eligible for refund.
Restricted destinations
We do not ship to P.O. boxes / freight forwarders / specific states or territories, if applicable. Orders placed to restricted destinations will be cancelled and refunded in full.
Order changes and cancellation
Contact support@nuflowlabs.com as quickly as possible. We can modify or cancel an order at any point before a shipping label is generated. Once a label exists, the order is final and falls under the Refund & Return Policy.
