Problem with nolva is it is a mixed agonist and antagonist to estrogen.
So, on some tissues it blocks the receptors and wont exert estrogens effects, but on other tissues like potentially the prostate I do believe it acts like an estrogen.
If what I suspect is right then there is some risk.
Due to the high risk of probable potential for prostate problems, between cycles I would deffo leave that alone.
I think you would be healthier and in some effects get the same benefits from cruciferous vegetables (Arugula, Broccoli, Cauliflower, Brussels Sprouts, Cabbage, Watercress, Bok Choy, Turnip Greens, Mustard Greens, and Collard Greens, Mizuna, Tatsoi, Rutabaga, Napa or Chinese Cabbage, Daikon, Horseradish, Radishes, Turnips, Kohlrabi, and Kale).
This not has mild anti-estrogen properties but also contains vitamins including vitamin C and folate, minerals including potassium and selenium, and also contain fiber, chlorophyll, as well as antioxidants, flavonoids and phytochemicals, carotenoids, lingnans, phytosterols, isothiocyanates, sulforaphane and glucosinolates (the sulfur compound that makes these veggies zing).
DIMM would be another option, but if we get to the root of the problem I think you would find that this would totally be a great solution, here goes.
As we age as men, out
testosterone drops, we tend to get more belly fat, the aromataze enazyme resides primarilly in belly fat, so the more bellyfat the more aromatase enzyme.
The more aromatase enzyme, the more conversion of
testosterone to estrogen.
Once the body sees too much estrogen, its only way of lowering estrogen is to trim off some testosterone. Net effect, lower test production and more estrogen.
When men are young, they produce about 10 times the testosterone of a women, and women produce many times more estrogen than men.
As we age, our testosteron to estrogen ballance changes, for the worse.
So, once women go through menopause, you are likely to have more estrogen than your female partner.
If that wasnt bad enough, it is suspect that the testosterone to estrogen ratio has something to do with the issues with the prostate.
I think many feel that it is testosterone or DHT, but young guys dont have prostate issues and older guys do. So, young men with raging hormones of testosterone dont suffer while the declining male hormonal guys do.
There is a fantastic product on the market called beta-sitosterol, I have noticed that when I take this product it cuts down night time urination.
I think it is about 300 times more potent than saw palmetto.
Another fantastic product which I found out accidently is fish oils, due to fish oils raising the anti-inflammatory prostaglandins, it actually made my urination flow much harder with more volume. I thought it odd one day that I could piss harder than a month or so ago.
After doing much research I found that the prostate has alot of prostaglandin activity, some prostaglandins are inflammatory like PG-2 (can elivate from AA), where as PG-1 and PG-3 are anti-inflammatory prostaglandins and this is where fish oils come to play.
Another thing, the prostate has the second highest amount of zinc in the body following the macular (eye) tissues.
In fact there is some evidence that points to macular degeneration and zinc deficencies.
Zinc is a mild aromatase inhibitor too and is helpfull in testosterone production.
Anyway, there are natural ways of doing things that probably should be looked into.
