You might recognize this from the “anti-estrogen” section and indeed this product can do double duty (which is actually more common than you think). Given at semi-low doses this is a great anti-aromatase and testosterone booster but given at much higher doses (400mg+ per day) this makes for a prohormone to the steroid hydroxy-testosterone. Hydroxy-Testosterone is a potent steroid in its own right, not quite as anabolic as testosterone, but still quite potent. Many people were taking straight OHT (hydroxy-testosterone) before it was banned in 2004, so we know that OHT can be anabolic. It is about 75% as anabolic as testosterone, but don’t let that fool you, at high doses Formestane is still a potent prohormone.
