Order received faster than expected. Choosing the fedex option makes it come a couple days faster. I cannot speak to how well it works because I won’t begin my research for several more days

Thank you for your feedback. We want to clarify a few important details to ensure accuracy.

Our warehouse and office were closed from 10/31–11/9, which was posted on our website banner and social media. During that time, no calls, texts, or emails were able to be answered. We did not begin responding to voicemails or emails until 11/10.

We reviewed our system and do not show any email received from you. Email is always the fastest and most reliable way to reach our team, and as of today all emails have been fully responded to. We are still working through the large number of voicemails and text messages received while we were closed, which is why phone responses may be delayed.

If you are missing an item from your order, please email us directly at orders@sjpeptides.net with your order number, pictures of the package, packing slip and what you received, and we will be happy to get this resolved for you right away.
