In vitro vs in vivoCurrently the testing is in vitro and that is what we are waiting for results on. My suspicion would be that they begin in vivo or at least have it lined up to commence by the time the in vitro results are released. Maybe the in vitro results are conclusive and don't require in vivo? I would not be surprised if the next news release says they have to do further tests for the proper certifications they are l for. Exciting times!
