Long term efficacy is one of the biggest thing that GNBT touts sets li-key apart. Perhaps they are continuing to look at each sample for additional evidence of that long term effectiveness - beyond a simple "did it nuetralize what we wanted it to nuertalize" test.
It's speculation, but could be one explain for why this testing seems to be taking longer than others might.
