Here's a question: Why does my pharmacy supplied (TRT script) test "freeze" and require heating to restore it to fully liquefied state, when my UGL test prop and mast (both E amd P) does not?? It's no big deal to deal with it, takes a couple minutes on the glass cooktop stove to make it ready to use, but the UGL supplies show no signs of crystalizing. So, what gives? What are the UGL'S doing that the "legit" lab isn't? Or vice versa?
