The Dangers of excess Estrogen.

Estrogen has a few misconceptions and hopefully this article will clear things up.
As an example, coffee boosts testosterone, but increases cortisol, cortisol lowers SHBG, and so you lower your testosterone estrogen ratio.
It isn’t elevated estrogen that is a problem, the reason is this, if estrogen is elevated, its likely Testosterone is too, and as long as the ratio for Testosterone to Estrogen is correct, EVERYTHING is ok, no need to worry.
In our youth The testosterone ratio can be around 50.1 that’s considered close to perfect. But anything around 30-40 is acceptable.
There are contributing factors as to why some guys are more prone to Estrogen related sides on a cycle.
These factors are.
High saturated fat diets.
Carrying a lot of fat weight.
There are also MEDs that can produce a marked change in Testosterone to estrogen ratio.
Using a PDE5 inhibitor
Using an Aromatase inhibitor.
Why is excess Estrogen dangerous?
Estrogen doesn’t cause Gynecomastia or GYNO for short!
Gyno is caused by an incorrect estrogen to androgen profile or ratio, the excess estrogen is trying to turn your body into a female, and as we are all aware the female characteristics most noticed are often larger breasts than in a male.
As long as the Ratio is correct this cant happen, The reason why people often suffer from rebound gyno, is they have very low test levels, and so your body is predominantly female. Hence the moods, etc.. or is that chauvinist?
The biggest dangers are the following..
Excess estrogen doubles your stroke risk.
This is a quote from the Mayo clinic
estradiol (a potent estrogen) were measured in a group of 2,197 men aged 71 to 93 years of age. Adjustment for age, hypertension, diabetes, adiposity, cholesterol, atrial fibrillation, and other characteristics were made. During the course of follow-up, men with the highest blood levels of estradiol had a 2.2-fold greater risk of stroke compared with those whose estradiol levels were lower.2This study revealed that estradiol blood levels greater than 34.1 pg/mL resulted in this more than doubling of stroke incidence. Life Extension long ago warned men to keep their estradiol levels below 30 pg/mL.”

Decreased Cardiovascular health

A study on middle aged men with high estrogen levels found out this very interesting observation made by researchers again at the Mayo clinic.

“Ultrasound measurement of the carotid artery wall provides an accurate prognostic indicator of arterial disease. The findings in this study show progression of carotid artery intima-media thickness in men with higher estradiol levels. Greater carotid artery intima-media thickness sharply correlates with increased risks of heart attack and stroke”

Increased risk of Rheumatoid arthritis

Levels of estradiol in rheumatoid arthritis patients are higher and DHEA levels lower compared with those who dont suffer from chronic inflammation. This corresponds to studies showing that high estrogen levels can increase C-reactive protein, which is the most accurate marker for systemic inflammation. Elevated C-reactive protein is an independent risk factor for coronary heart disease in healthy individuals.
The list goes on and on.
Low fat diets for better Test/estrogen ratios 
We are all aware, that high estrogen levels cause you to store more fat, which doesn’t look good and ist healthy.
But did you know the diets high in saturated fats, especially on steroid cycles can play havoc with your Testosterone estrogen ratio?
Most people think low fat diets are not good for keeping your sex hormones optimal, but research and science actually shows otherwise.
One study found that                                    estradiol (the “bad” estrogen or E2) fell from 47.2 to 23.8 pg/ml                         on average, which is obviously a big change.                          This is a reduction of over 50% and cut their estrogen levels in half!  And the remarkable thing is that their testosterone stayed steady before and                         after at 510 ng/dl.
So instead of damaging their testosterone ratio, their test stayed the same, and estradiol dropped! Improving their ratios, actually it nearly doubled the ratio in favour of Testosterone.
On a steroid cycle high fat diets not only affect the amount of estrogen converted , but decrease the effectiveness of the steroid cycle, and the health implications of higher estrogen and excess fat have already been outlined above.
Being Fat
You wouldnt be surprised to find that people with a BMI above 25, and below 25
when compared often have an estrogen ratio difference of about 12 – 17, which corresponds to a 42 percent difference in estrogen.
However we all know that most bodybuilders BMI will make them obese, even if they have very low bodyfat. In my previous articles we would of seen that the more aromatase the more estrogen and the more estrogen, the less testosterone.
 Excess body weight is correlated with both lowered testosterone and increased                         estrogen.  Stomach fat actually deactivates DHT, and it converts at greater amounts the more layers of belly fat you have to,  5alpha-androstane 3alpha 17beta-diol this is a very potent estrogen as is 5alpha-androstane 3beta 17beta-diol, The longer you’ve been fat, the greater the enzymatic deactivation of DHT and the greater the conversion into these potent estrogens, Both of which are responsible for increased water retention, leading to higher blood pressure! Ever wondered why your blood pressure often spikes on a cycle, Well if your fat this might just open your eyes.
The less body fat you have, the better your testosterone estrogen ratio will be during the steroid cycle. And of course after during PCT.
The benefits of a PDE5 inhibitor.
If your a little overweight, or struggling with your libido and erections, then your self esteem lowers, And time and time again after a steroid cycle, and during ive seen guys crash, this is nearly always because of excess estrogen, not elevated estrogen. I hate all this bro science garbage, get it right guys, estrogen is important for libido, if your libido is gone its either, your Testosterone estrogen ratio is wrong, so either too much test or too little estrogen, Or the other way around. Or very little DHT conversion or activation, if your fat this is likely along with having a poor estrogen ratio. Prolactin is very rarely is the culprit unless you have used a Nor-steroid, like Deca.
Using a PDE5 inhibitor causes an increase in nitric oxide, bam, You are able to have sexual intercourse, One study showed an improvement of the estrogen testosterone ratio by a staggering 24% after sex.
 What is very interesting is                         that in the above study, testosterone only increased 5.5% on average but                         estrogen lowered by about 15%. So if you cant get an erection, a PDE5 inhibitor mare really help your post cycle crash, if you don’t need one, sex could be your biggest help.
Using an aromatase inhibitor
For arguments sake lets use Arimidex, its a really well known A.I
In a well documented study it showed that in hypogonadal                         senior men, the T/E ratio was increased on average by 115%.  It produced an increase of                         62% in testosterone and a 24% decrease in estradiol.
On a cycle where there will be a large amount of conversion to estrogen, it might not be needed unless you see the signs of high estrogen levels, water retention, high blood pressure, then dosing accordingly is important, you don’t want to kill your estrogen levels, not only will it hamper gains, but no estrogen is very very bad for your health, and causes a tremendous amount of internal damage.
All you want to do is keep the ratio to a healthy level, so don’t leave things to chance, regular check ups are needed.
If you destroy estrogen, it comes back with a bang when you stop taking you A.I, and that can pose a big problem, as it comes back much harder than testosterone does, throwing your ratio in favour of estrogen and leading to rebound gyno etc.
So tapering off your A.I during PCT is a must, its not bro science, it is a science, and anyone who says otherwise should not be handing out guidance.
There are many other causes of GYNO but here we are just looking at excess estrogen.
As long as testosterone is always higher by about 35 percent than estrogen, your health and libido will rarely suffer, if you have a healthy bodyfat level, if you don’t then lose weight, and you might be surprised to see a large increase in your baseline testosterone levels.
Until next time, stay safe, and keep that excess estrogen under control.
