PGF2A made @ home?

This may be a dumb question but its my first....If you could get a Doc to get you the injectable Dinoprost which I understand is used for abortions. Could you mix with DMSO yourself, and apply? If so how exactly how would you do this? Amounts?

you can buy transdermal PGF2A real easily.

But if you have access to the injectable version, why wouldnt you want to inject it?
