The Van Pen I'm familiar with is provided by PCCA.  You can find them on the
web at pccarx.com.  It is my opinion that Van Pen is a cream base similar to
Vanicream or Dermabase-but I may be totally off base here.  You can use
Vanicream as a base to put testosterone in for topical use-it's much better
that the old formula with Vaseline.  There is also a product called PLO gel,
which can be used as a base for testosterone, it increases the systemical
absorption of the tesosterone-usually used in topical testosterone preps for
men-women usually don't need such high levels.  PLO gel (looks like a cream) is
available from several different companies-Spectrum is one that comes to
mind-called "Transderm PLO". (No relation at all to PCCA or Spectrum-just a
compounding pharmacist).
