There a Thai ugl that's been around a long time and most all Chinese suppliers sell it must be cheap in china, so take it for what it's worth I've used it before it was just ok I tried the test cyp. The board at meso now has a legit mass spec website tested HPLC gear by ugls I was surprised by how many brands were actually legit I've run many of them and thought they were weak or no good so all that bro science went out the window only real science is the answer especially very popular ugls. It's funny to listen to all these keyboard warriors go on and on about brands of gear and they don't know shit all bro science or the truth believe no one except the real tested gear. U.S. The site is crowd funded no agendas.
