I spent a little time yesterday trying to determine the half life of Formex. After my bit of research, I discovered it is approximately 7-9 hours.
My reasoning behind this was from the studies done on E2-MCPE comparing it to regular E2. First off, it showed amazing oral bio-availability due to the MCPE Ether. Secondly, it showed to have a half life about 3-4x that of regular E2.
I took this information, and made the rough estimate that Formex has the half life of 7-9 hours since regular formestane has a half life of 2-3 hours when taken via oral route.
