Shipping Policy

Shipping Destinations. We ship to addresses within the United States. If we are unable to ship your order, we will notify you and issue a full refund.

Order Processing. Orders are processed within 1–3 business days of payment confirmation, excluding weekends and holidays. You will receive tracking information by email once your order ships.

Carrier. All orders ship via USPS. Estimated delivery times are provided by the carrier and are not guaranteed. We are not responsible for delays caused by USPS, weather, or other circumstances outside our control.

Shipping Costs. Shipping is free on all orders over $50. Orders under $50 are charged shipping at checkout based on weight and destination.

Storage on Arrival. Our peptides ship in lyophilized (freeze-dried) powder form, which is stable at room temperature during standard transit — no cold-pack shipping is required for the powder. Upon receipt, store lyophilized vials according to the instructions on the product page (typically refrigerated for long-term storage).

After Reconstitution. Once reconstituted with bacteriostatic water, peptides must be refrigerated and used within the timeframe appropriate for that compound. Reconstitution and storage after mixing are the responsibility of the researcher. Improper reconstitution or storage after delivery may affect product integrity and is not covered under our refund policy.

Lost Packages. If USPS tracking confirms your package as lost in transit, contact us at [YOUR EMAIL] with your order number and we will issue a refund or replacement.

Damaged or Incorrect Orders. If your order arrives damaged, incomplete, or containing the wrong item, contact us at [info@superiorpeps.com] within 7 days of delivery with your order number and photos of the item and packaging.
