No, you will probably not see it commercially available. At least not in the next 10 years.
Why?
The reason is probably money.
Prostarkan have done Phase2 trials and have it available for licensing. Pzifer have developed their own RU, that they are testing. They will probably not pay Prostarkan for something they can develop their self. RU have been said to not be so easy to keep "fresh", so that could be another problem.
Another reason is that many think finasteride is good enough and that "something" big will happen in hair loss research the next 10 years, so why use millions of $ to release a drug that won't earn a lot because something better comes along?! Merck really don't make a lot of money of Propecia in the big picture. I guess a lot of firms are holding their breath to see if ARI, Intercytex Proto-hair, Follica, Histogen, Neosil and AndroScience have any good results. I believe in that we will see amazing research and drug-development in the next 10 years, but maybe not cure hair-loss, but certainly get better meds. WNT-protein is something many researchers are looking into. And many researcher are saying that anti-androgens are effective, but many people need a little extra. Dr. Proctor have said that he puts lots of different ingredients in his Proxiphen just to give people more "attack-points" on their hair loss, so they have a bigger chance of getting some success. Remember that it's not just DHT that damages your hair, researchers are know trying to look into it all and they are moving slowly forward.
One could even discuss that topical anti-androgen is not as effective as internal. Some(remember, just some) RU users have complained about RU losing it's effect after 2 years. But this is highly discussed and no one really knows the answer. This could maybe be connected to the AR being multiplied or become more sensitive. No one really knows. I just hope some users just got a bad shipment.
I don't think ProStarkan has released anything about their research about RU, so we don't really know how good it is in a big study. We know it have nice results for some people, but for all we know it's not really the superdrug we hope for. People will always want something they can't have, if you know what I mean. If RU was as effective as the hedgehog project I guess Donald Trump would bring his Alligator suitcase with cash.
If you are willing to bang out 150$ every month on one drug, I would test Proxiphen, just because is a good combo and easy to apply.
