what did your Dr suggest? i'm surprised they didn't put you on a Rx aromatase inhibitor, or get additional bloodwork....
here's what i'd suggest, and why.
i would not take a SERM in this situation, since your E2 is so high. a SERM won't fix it, and might make it a tad bit worse... also, there are 2 main negative feedback mechanisms acting on the HPTA: androgens, and estrogens. if either one is high, then they will suppress testosterone production.... in this case, your estrogen is crazy high, and will continue to suppress your HPTA until you can bring that down... (the only reason to take a SERM now, IMO, is if you are getting gyno, and i'd suggest running raloxifene for that).
your liver values are high (ALT), and that could be from the prohormone, from your high estrogen, or both. anyway, since your liver metabolizes estrogen, you need to get that functioning better so it manages your estrogen better. i'd suggest phosphatylcholine (500 mg/day) and TUDCA (500 mg/day) and see how that works.
also, you need to make sure you getting enough zinc, magnesium and Vitamin d to optimize your hormones; in this case, lower your E2 and raise your testosterone. if you're not doing so already, i'd suggest getting some ZMA and Vitamin D, as well.
and finally, get an AI.... personally, i like Aromasin (25 mg/night w/ meal). it might not do the trick here, but it is the fastest acting.
