Question: What are the delivery time and transportation method?
Answer: After receiving your payment, we will send the package to you via United States Postal Service, FedEx, DHL Parcel or other designated transportation methods. It will take approximately 10 to 15 working days to reach your address.
Q: How should the peptide be stored after receiving it?
A: The freeze-dried powdered peptide can be transported at room temperature in vacuum packaging, while the dissolved peptide needs to be refrigerated at 2℃ - 8℃. For long-term storage, the freeze-dried powdered peptide should be stored in a sealed container with desiccant and placed at -20℃ or -80℃, which can minimize the degradation of the peptide to the greatest extent.
