Not surprising. Formex reduces estrogen by binding to the aromatase enzyme permanently deactivating it. This takes about 2 weeks to reduce the estrogen in your body (very rough estimate but it certainly wont reduce estrogen immediately). There would be a sh1tload of estrogen in your system already from your cycle because you haven't been taking an aromatase inhibitor ... the estrogen is free to form using your massive amounts of test. Nolva doesn't reduce estrogen ... just stops it from growing gyno. So ... if you can, continue nolva, stop your Test cycle, and continue formex and your estrogen should slowly go down.
