In my view - Anavex does not have much in-house knowledge or knowledgeable people
They got 2 compounds and they trialing it for years without going much further
Missling likes to talk about some key words and concepts but A2-73 not proven anything. So they are not in a position to prove if A2-73 works.
A3-71 is a mystery and as they say a treasure is worth millions of dollars till it is hidden in a box and not found. Once the box is discovered and opened it may be worth $100 - so Missling will go slow till he can keep on saying that it is more effective than A2-73
