This policy covers processing timelines, carriers, risk of loss, and what to do if something goes wrong in transit.
Orders are typically dispatched within 1–2 business days of payment confirmation. Business days are Monday through Friday, excluding US federal holidays. Orders placed on weekends or holidays begin processing the next business day.
You will receive an email confirmation when your order is placed and a second notification with a tracking number once it ships.
We ship via USPS, UPS, and FedEx. Carrier and service level are selected automatically by our shipping system based on rates and delivery estimates at time of dispatch — this is not a manual or discretionary choice, and a specific carrier cannot be requested.
Standard estimated transit times within the continental United States are 2–5 business days from the ship date. Expedited options may be available at checkout.
All peptide products are lyophilized (freeze-dried) and sealed in labeled vials. Because lyophilized peptides are shelf-stable at ambient temperature, orders ship in standard packaging — no coolant or cold-chain handling is used or required.
Shipping costs are calculated at checkout based on order weight, dimensions, and destination, and are shown before you complete your purchase. Once your order is placed, the shipping cost is final — it will not change or accrue additional charges after purchase.
Title and risk of loss pass to the purchaser upon handoff of the shipment to the carrier. Just Peptides is not responsible for delays, damage, or loss caused by the carrier once a package has been tendered for delivery.
If your tracking information shows a package as delivered but you have not received it, please check with neighbors and building management first, then contact us within 48 hours. We will work with the carrier to investigate.
At this time, Just Peptides ships to addresses within the United States only. We do not ship internationally. This policy will be updated if international shipping becomes available.
If a package is returned to us as undeliverable due to an incorrect or incomplete address, we will contact you to arrange re-shipment. Additional shipping charges will apply. We are not responsible for packages returned due to address errors entered by the customer.
If your order arrives damaged or with missing items, contact us within 7 days of delivery at contact@justpeptides.store with your order number and photographs of the packaging and damaged product.
We will arrange a replacement or refund at our discretion. Claims submitted after 7 days of confirmed delivery may not be eligible for a remedy.
