If 3 71 is better, why are they wasting time on furthering trials on 2 73? I am not sure what is going on. I invested because of the great hopes for 2 73. Is it not strange that a company comes up with a great product but before it is approved that same company claims to have another great product to surpass their first discovery? I am still confused. It is looking like the news is too good to be true.
