@youlied, you posted that pic as a reply to every recent thread. If you were trying to prove you are a total psycho, congrats, you succeeded in compelling fashion. If that is your penis, I\'m very sorry for whatever you chose to do to yourself. But I doubt that came from any doctor recommended in this forum.
@skinny, to answer your question, there are a number of factors when something becomes FDA approved. Someone must benefit from the incredible expense and risk in attempting to acquire approval (there\'s no guarantee that applying for approval will result in approval).
There are very few US physicians skilled in using dermal fillers in the US with a consistent track record of success. Using
PMMA for dental, bone, and other applications is FDA approved, and has a long list of success stories.
For LS or MC to attempt to get it approved, they would need confidence that a notable number of US-based docs would actually use it. Currently, there is no outcry in the US demanding these products, and therefore, the initiative is not taken to get it approved.
If it were approved, expect the prices to be far higher than they currently are in Mexico or Prague. The increase in price would not be an increase in profits, but an increase in administrative expense required by it being FDA approved.
