My simple answer is that I do not know
I've seen the arguement from both sides in regards to drol, but both are pending on the research that is available, which isn't very much imo...or at least with strong conclusions.
I've heard from users that Nolva helps, while others state that it did nothing and only cabergoline helped. I'm not big on running nolva with progestins (ie pgr upregulation), but if it works, then I wouldn't necessarily drop it 's use either.
The studies performed from a long time ago are very weak, and not reliable imo. Before AI's were available, we used Anadrol a lot back in the day, and those who were sensitive to it's sides, Nolva did nothing for them. This was back in the Nolva/proviron only days...lol.
So if it worked well by it's actions as an anti-estrogen, while drol acts like an estrogen, then it should have eliminated their gyno occurences. Now, that isn't set in stone either imo because others have stated it did work, and even more guys stated it prevented gyno from once applied when in the past without it, they did receive problems. So again, their is a conflict on the 2 sides here
With drol, if you are sensitive, then maybe the best course of action is no action of it all. It's a tricky compound imo for this exact side. Some may never get signs of gyno though, but those who do, it usually developes VERY quick out of nowhere. Keeping the doses on the low end also helps.
So all that being stated, and I didn't really add much with all of it in regards to answering the question.....maybe both Nolva and cabergoline is best suited for it....pending on whether it increases PgR expression, at which point nolva would not be beneficial.
An AI should be used during this if on test or dbol imo. I'm a big advocate of always having at least 'some' test in the equation.
The arguement between whether anadrol acts like an estrogen or a progestin, I can't say for certain now though. I'm partial to it acting as a progestin though...slightly.
