I agree, this is a widespread problem , it's like 10% to 15% of the population who is affect by T.
2020 sound like a very (very) likely deadline considering the financial stakes and I do believe that we will get some stuff way before that.
The AM-101 is a first step for acute T. and is already in phase 3 with good results in phase 2.
The AUT00063 is very promising for chronic T. and is about to start phase 2 and I expect a lot of us to have early access to this drug (if woking) by the end of 2015 in a large scale phase 3.
More is coming with this virus found that helps mamals to regrow haircells, or the numerous research projects in most major pharma group.
I am not worried at all, and I know that each day is a day close to a cure.
