The Peepack is an awesome product. I love that it is so much easier to maintain temperature than any other product in the industry. I have used the Peepack numerous times and always passed with flying colors. I do know that their company Globolic Technologies uses a higher grade type of sterile urine that is preservative free and carries the pharmaceutical grade urea required for the strictest of tests in Canada & the US markets. My urine samples where I am tested are sent directly to the lab for very intensive testing, and I have always passed. I love their products and suggest checking out all their stuff.
