There is NO one-size-fits ALL protocol!!!
That said, if I am to employ any type of anti-estrogenic, it would be Clomid.
As for Nolva, reasons NOT to make this your first choice:
(1) Decreases plasma levels of IGF-1 (this is really a pro-estrogenic effect as estrogen renders the liver less sensitive to GH - by decreasing density of liver GH receptors
(2) Pro-estrogenic at the level of the muscle tissue (concomitantly with #1, this is a horrendous 1-2 punch for any muscle gain).
(3) Acts as a signal to protect muscles (kind of like an anti-oxidant)...would be good as suggested in ANY group outside of bodybuilders and namely around a workout period due to cytokine employment being attenuated.
Not to mention all the erroneous dosing parameters suggested by the masses and the internet "gurus" that suggest Nolvadex + DHEA is a good idea (when DHEA completely wipes out Nolvadex's actions anyway!).
With some of the multi-million dollar regimes emeshed in people's apparent budget, invest in some A-zole or Letrozole or even OTCs, but really focus on the AI, couple this with an estrogen-modifying agent like I3C .... NO NOT DIM (which has virtual crappy bioavailability when financially invested groups aren't involved in the research!!!).
And for more reality, continue to watch PCT:ACV subforum above!!!
