Well at least you havent made wild claims with this, i enjoy studying extracts that contain androgenic and estrogenic effects, this one doesnt have many studies on it, im not going to critique this, as only an idiot says it cant work before proper human trials are conducted, and its shown real promise in logs.
Tinospora Cordifolia would seem to bind specificly to androgen receptor cells in the prostate as studies suggested a proliferation of LNCaP cells wich im not sure is a great thing as that causes prostrate cancer, im guessing your extraction process focused on getting the active 20 beta-hydroxyecdysone wich also isnt very biovailable.

Things though are not always what they seem on paper, and i hope that this shows more promise than studies suggest, BTW this is not the only plant extract that expresses androgenic effects, there are others with a lot more studies, and formestane is a prohormone to 4 hydroxytestosterone wich is a steroid, and mild A.I.
I will be watching the logs closely, and hoping for the best, id love to test this out myself, wich i will soon.
