im thinking about making a transdermal. what im wondering is how do i make a transdermal and from what i read a transdermal has a 12 hr steady release period and about 20-45% of it is absorbed. and utt and nasal delivery has 3 hr release period and about 60-90% is absorbed. i know where to get 11oxo i powder form but are other ph powders easy to obtain? evertime i google search them i always get linkes to tradekey.com. can some1 pm or give me key words to google search for powders? sorry for so many questions.
oh and what is it delivered through and how do you know what the mg/ml is?
