The peptides are of good quality and come with complete 3rd party testing reports. They have a very helpful information website that explains every product in detail and exactly how to use it. I called and spoke with someone personally as well as used the chat feature and both were able to answer my questions. There is so much bad information and unpure products out there. It is important to find a company like this to support you through the process. I have recommended to many of my friends.
