Try checking out the board sponsors. You will see that ag-guys.com, ***********.com, and other innovative-research.com sell clen for "research purposes" only. Some of the sites also state that the product should not be injested by humans. Again, these sites provide liquid clen for research purposes only. For future reference, the board doesn't allow the asking of sources and what not. I've found this out several times... Good luck with your research!
