Crashing your E2 when you're body is struggling to restart and produce testosterone is not the brightest move, imho. Serms, clomid in particular, already trick the hypothalamus into thinking there's no estrogen and thus it ramps up production of GnRH in effort to stimulate the pituitary. Reducing your estrogen to an unhealthy level may temporarily allow a small rise in T levels but it's short lived and uneccessary considering how you may feel doing so.
