Packaged discreetly and on the truck within 1 business day of every order.
Currently, all 50 U.S. states. International shipping is not available — peptide customs rules vary widely by country.
Pick your speed at checkout:
Most orders ship within 1 business day of payment confirmation. We aim for same-day on orders placed before 2pm EST when fulfillment volume allows; orders placed after that, on weekends, or during high volume ship the next business day.
We ship via USPS Priority and UPS Ground. Tracking is included on every order and emailed to you when the label is created.
Every order ships with free shipment protection. This isn't a return policy — it's our guarantee that the order you placed actually arrives in the condition we shipped it. We will reship at no charge if your package is:
Email support@helixcorebio.store within 14 days of the expected delivery date with your order number and, for damage claims, photos of the package and contents. We respond to every claim within 1 business day. If we sent the wrong item, dispose of it per your lab's standard practice — please don't ship it back.
We'll refund to your original payment method only when reshipping isn't possible — for example, if the product is permanently out of stock. Refunds are issued within 5 business days of approval.
Lyophilized peptides are stable at room temperature for transit. For long-term storage, refrigerate at 2–8°C or freeze at −20°C. Avoid repeated freeze-thaw cycles.
We ship in plain, unmarked outer packaging. The shipping label lists "HelixCore Biotech" as the sender — there is no product name, sequence, or research material indication on the exterior.
