First it was operation gear grinder. From their they found out that China was the connection. So for 2 years or so they began operation raw deal. The companies that these UG labs buy from are the same companies the research companies buy from. Obviously, China is one of the best places for pricing. The IRS got involved in a lot of undercover operations and a few research companies got mixed up because they didn't pay taxes or were selling research chems while registered as a human grade supplement company, or talked about how to make gear, etc. Any research company that went down who was not an underground lab was just stupid or running something on the side. Than President Bush signed an agreement with the Chinese government in May that the Chinese agreed to strip licenses and come down on their pharmaceutical companies who export controlled substances in the US. So most of the Chinese Pharmaceutical companies do not want their licenses suspended, so they will not send into the US. Of course there are always going to be exceptions, but for the most part the US had a hand in the UGL's closing shop. If the supplier will not send any more, no UGL. Yeah right, lol, people are just going to be a little smarter I hope. All this was bound to happen as stupid and careless as everyone became over the past 5 years.
