1.8gr to 2gr
Assuming a rounded level of hormone penetration through the dermis set at 20 - 25% would yield roughly 40 - 50mg of dhea to the bloodstream. Given the conversion rates of dhea metabolites(androseries write up) the following amount of testosterone would be present at that given dose.
6.2% of dhea converts to androdione equaling 2.48 - 3.1mg
7.5% of Androdione converts to testosterone equaling .186 - .233mg active testosterone
7.2% of dhea converts to androdiol equaling 2.88 - 3.6mg of active adiol
6.2% of adiol converts to testosterone equaling .179 - .223mg active testosterone
200mg of transdermal dhea equals .365 - .456mg of active testosterone per dose.
It could be skewed a little bit as I am just going by a random round number for penatration and the given conversion rates.
