Estrogen, SHBG, Aromatase & Free Testosterone

by BM

Estrogen, SHBG, Aromatase & Free Testosterone

Hi Mark,

My estrogen levels are at 45.

Free testosterone % is below normal and total Testosterone is 800.

I am a very healthy and fit 43 year old male.

I have the classic high Estrogen symptoms, except no man boob problems.

Just lack of energy, low libido and the worst is weak erections, all taking place beginning of this year.

Took arimedex on the advice of a urologist. He thought I had prostate problems, but I didn't.

No real changes. Estrogen dropped only 4 points after 3 months of .5mg per day.

Do you think your plan could be helpful?

Thank you very much!

Estrogen, SHBG, Aromatase & Free Testosterone

Hello BM,

Yes, I think my plan would be helpful... with a few modifications of course.

My gut tells me you've got two things going on here..


Sex Hormone Binding Globulin is too active in your system.

The fact that your total testosterone is 800, but your Free T is below normal is pretty solid proof of this fact.

The reference range for SHBG is between 13-71, but I personally like to keep mine below 30 at all times.

I'd bet my hard earned cash that yours are at 40 or more based on your lab numbers.


Chances age good that aromatase is extremely active in your system, converting your testosterone into estrogen.

Your E level of 45 is decent proof of this, even though that number does fall well within the reference range.

My experience has shown that anything over 30 puts you in the danger zone.

Slide above that number, and sexual negativity will most certainly come knocking on your front door.

But you're a lucky man!

At 800, you've got optimal total testosterone levels.

All you need to do now is ensure that your body starts doing the right stuff with your juice.

In other words, get a grip on your SHBG and aromatase levels, and your problems should be solved.

Estrogen, SHBG, Aromatase & Free Testosterone

I'd start by cycling the following supplements...


This supplement blocks aromatase activity, which slows the conversion of T to E in your system.

One study showed that chrysin was as effective as the anti-aromatase medication, Cytadren.

Nettle Root

This supplement blocks test to est conversion. It also occupies sex-hormone binding globulin, which frees up your bound testosterone, and makes it available for use by your body.


DIM converts nasty estrogen's into good one's and processes toxic estrogen's through the liver where they are excreted out of the body.


Eliminate soy from your diet entirely.

If you drink, do so in moderation. If beer is your beverage of choice, switch to a distilled spirit like vodka.

Also, add cruciferous vegetables like broccoli cauliflower, and cabbage into your diet.


Take steps to avoid estrogenic chemicals in your environment.

Cycling Dim Chrycin Nettle
by: Anonymous

Since I'm currently cycling the 7 supplements that you recommend on your site and then taking two to three days off I'm thinking that cycling the 3 aromatase inhibitors on those off days would be a good strategy. Any thoughts?

Hi there,

Yes, if you're experiencing tender, sore, or sensitive nipples, difficulty getting your urine stream started at night, or unusually high testosterone levels, which will increase the conversion of testosterone into estrogen in your system.


Taking aromatase inhibitors and testosterone boosters
by: Anonymous

Should the aromatase inhibitors be taken at the same time as the testosterone boosters?

Are both the testosterone boosters and aromatase inhibitors taken with food, or on an empty stomach?

Hello Anonymous,

Lately, I've been taking my aromatase inhibitors and testosterone boosters in the morning, all at the same time with a little bit of food.

Works perfectly for me.

Fenugreek for aromatase
by: Anonymous

In another post you mentioned fenugreek as a potent aromatase inhibitor.

How would you cycle fenugreek with chrysin and nettle root? What is the most they can be used in a week without losing their effect?

Hi There,

If it were me, I'd cycle the 3, taking each for one day before moving on.

Add DIM to the mix, and you'd be covered 4 days out of every week.

But keep in mind, you don't take the E blockers just because.

You use them only when you need them.

For example...

If you have difficulity getting your urine stream started at night.

You are experiencing tender, sore or inflamed nipples or breasts

Your Testosterone Boosters kick in especially strong.

If you're 20 pounds or more overweight, these supplements could be used daily to shut down the aromatization of testosterone, but weight loss would be a more effective strategy.

Good luck!

Cycling DIM
by: Anonymous

Since DIM is a food constituent, as opposed to an herb,is it necessary or beneficial to cycle it, instead of taking it regularly? I'm thinking we don't cycle cruciferous vegetables.

Hello there,

You won't build up a tolerance if you don't cycle it, but I still would.

I think it's a bad idea to take any supplement, day in and day out for years and years at a time.

I'd feel pretty comfortable taking it a few times a week though.

Cycling Chrysin, DIM, and Nettle Root
by: BM

Hello Mark,

What would be the best way to cycle Chrysin, DIM, and Nettle Root based on your experience, and how long does it typically take to see a decrease in high estrogen and SBGH?

Thank you very much!

Hello BM

Cycle through all three, taking each for one day, before moving on to the next.

But, only take them when you really need them.

For example, when you have difficulty getting the urine stream started at night, if your nipples are sore, itchy or inflamed, or if you are experiencing testicular atrophy.

The positive effects should come on immediately, unless you are severly overweight.

If so, you need to make weight reduction a high priority.

Good luck!

Response to Mark's Recommendations
by: BM


Thank you so much for your timely response!

You are on the money with all of this.

After I posted my question, I remembered that I forgot to give you the number for my SHBG.

In your response, you said it is probably higher than 40, and mine is almost above the normal range.

A definite clue that you really are very knowledgable with this information.

I will cycle the anti-estrogen supplements as you recommended.

Thank you so much!
