PN is carrying the Dermabolics Transport Matrix to mix your PH's. It's kind of expensive though. You can find it for $12.99 at another place. BDC makes the T-Gel, which is Chemo's company. It has been said that there has been trouble getting one of the ingrediants for the formula.
Don't worry, I'm sure it will be available once again. People will still use the T-Gel long after the ban.
