I placed an order for five peptides and when the package arrived, I noticed one vial was missing. I was honestly expecting a long back-and-forth, but that didn’t happen. I sent them a message and got a reply pretty quickly. They checked it, admitted the mistake, and shipped the missing one the next day. Once it was handed to FedEx, it showed up literally the following day. That kind of turnaround says a lot about how they handle issues.
