No way to tell exactly what it is without removing it. My GA70 came with a factory LSD, I dont know what the exact ratio is but most of these a70s came with quite high ratios. Im expecting it to be something along the lines of 4.1+:1.
If your friend is the one trying to tell this lsd on supraforums tell him to lay off the drugs or get a clue if he wants people to take him seriously.
