Shipping Methods
Available shipping options depend on your cart. Single-vial, kit-only, and mixed (kit plus single vial) orders use different carrier tiers as shown at checkout:
| Cart type | Method | Carrier / service | Rate |
|---|---|---|---|
| Single vial | Economy Shipping | USPS Ground Advantage — 5–10 business days in some locations | $15 |
| Single vial | Standard Shipping | UPS Ground, USPS Priority Mail | $25 |
| Single vial | Express Shipping | UPS Second Day Air — No Weekend Delivery | $35 |
| Single vial | Overnight Shipping | UPS Next Day Air Saver — No Weekend Delivery | $50 |
| Kit only | Standard Shipping | USPS Ground Advantage | $20 |
| Kit only | Overnight Shipping | FedEx Overnight — No Weekend Delivery | $65 |
| Kit + single vial | Standard Shipping | USPS Ground Advantage — two packages (kit and single vials) | $35 |
Shipping Rates
Shipping rates are calculated at checkout based on your cart contents and selected method. Kit and single-vial items ship as two separate packages via USPS Ground Advantage. When kits in the same order ship from different warehouses, each warehouse is a separate shipment and a separate kit shipping fee. Example: one kit from one warehouse and another kit from a second warehouse is two kit shipments — Standard $40 or Overnight $130. A mixed cart (kits plus single vials) starts at $35 and adds $20 for each extra kit warehouse. The rates shown in the table above (and on the checkout page) are the current published one-warehouse rates.
Tracking
Tracking numbers are emailed when your order ships. You can also enter your carrier tracking number in the AfterShip tracker in the site header. For order-status questions, email orders@nextdaypeptides.com with your order number.
Delivery Times
Overnight Shipping and Express services do not include weekend delivery. Overnight example: order Sunday, ship Monday, receive Tuesday. Economy Shipping uses USPS Ground Advantage and can take 5–10 business days depending on location. Transit times vary by carrier, destination, and service level. Weather, carrier delays, and incorrect addresses may affect delivery.
Risk of Loss
Title and risk of loss pass to the purchaser when the order is delivered to the carrier. Report shipping damage within 48 hours of delivery.
