Well, I went ahead and ordered several kits last night. I liked the ease of the website, much like Amopure, but they had so many more products. I already got tracking this morning that the label was created and free shipping was nice. I am going to test at least a few of them to make sure the reports match fairly accurately and test sterility. I noticed the GHK-cu didn't have a COA on the website but we'll see what the packaging has on it when it arrives. Primarily I wanted BPC-157 for my dog, they say it helps tremendously with joint issues in pooches. Some reports say check for signs of cancer as it can exacerbate it, some say it's extremely safe. I'm taking her for a full check-up before I do anything major.
