What you guys use and does anyone know where we even started using gso. Does anyone know anything concrete about why to use one over the other? I was using gso for a long time then saw that pfizer document floating around and they use cso in their test. I tried some making test cyp....it was awful to filter! I had to use 3 filters for 100ml cause it was so slow, just would not go through even after warming it up
