FDA busting ALL 15% Minoxidil? Expiry dates?

Interesting, the first dermatologist I saw said they could mix up to 20% minoxidil for me. To me he seemed all about the $$$. He charged $425 for the consultation alone.

I don't know how much trouble you want to go through, but Minoxidil is a crystalline powder dissolved in the water/alcohol solution, and it has a very high melting point and decomposition point. If one were to boil off 2/3 of the liquid, you would be left with a 15% solution.

Furthermore, just applying 3 ml would probably have the same effect.

In addition, it might be more beneficial to increase the dose to 1 ml of 5% 6 times a day vs two 1 ml applications of 15%. Only a study would say for sure.

Edit: Wait, I just read that due to solubility issues, the concentration of Minoxidil in water/ethanol without additives cannot exceed 7%. One can still apply more 5% solution at once, though.
