Are you sure about Letraron? Formestane is an anti-E, more specifically an aromatase inhibitor. Someone had mentioned the possibility of formestane acitate being different than the formestane used in cancer treatment, but I'm pretty sure they're the same thing.
I know for clinical purposes they administer a 250 mg dosage every two weeks for effective aromatase inhibition, so that leads me to believe that it can get into solution somehow, because there's no way they're jacking these patients with a bigass 3+ cc IM injection every two weeks. After one administration of a 3+ cc shot, the patient would be like "**** this" heh
