Making your own "transdermal homebrew" is not as easy as it might sound. A cyclo intranasal, yes, but transdermal...
DMSO is a possibility, but I don't think aloe would do much for you. I'm no chemist or physiology expert, but I'd rather go with a product someone who knows their shit has researched and developed, and is known by others to work well. That being said, I've heard the best results come from AndroSpray and Avant Lab's 4-ADerm. Combine it with intranasal or oral for a nice cyle.
