Absolutely superb customer service; I was having a bit of trouble with my credit card and they helped me right away. As far as the peptides are concerned, they have all of the chemistry/lab tests online so as to test for purity, you don’t even need to request them. I received my order within the week and was so pleased that I ordered again the following week to be sure that I had plenty on hand, I have also referred my friends; fabulous company and thank you.
