Prevent

Does anyone know the milligram amount of Formestane in 'Prevent?' I ask because I'm comparing e-form vs Prevent in terms of quantity of ingredients. Prevent sells in a 2oz container vs e-forms 4oz, yet prevent sells for 10 dollars more. e-form simply has formestane as the main active ingredient. Prevent, on the other hand has 3,6,17-androstenetrione, 4-hydroxyandrostenedione, caffeine anhydrous, synephrine hcl, octopamine hcl, tyramine hcl.


Thanks
