What Is Steroid Aromatization



What Is Steroid Aromatization

When taking steroids, there are a number of processes that happen in the body. Along with anabolic effect, steroids may cause some serious side effects that every bodybuilder fears of. Most of them are estrogenic issues caused by the strong aromatization.

Bodybuilders search on the internet for low aromatizing steroids or even for those who do not aromatize at all. This is a wrong approach since all steroids aromatize but in different degree.

To better understand why all steroids carry the risk of aromatization and how bad it is for your health, you will have to know, first of all, what aromatization means, what causes it and how can be prevented its downsides. Yes, downsides, since generally it is good to process for body and you will see in this article why.

Aromatization is not triggered by steroid use. It is a natural process during which testosterone is transformed into estrogen. This process is carried out by a special enzyme in our body called aromatase, thus the whole processed was called aromatization. The main task or aromatization is the synthesis of cholesterol and fats. But it changes when the body feels a testosterone boost.

The human body has a very interesting characteristic: it tends to ensure a balance in all it has-muscles, hormones, temperature, and others. This stage is known as homeostasis. When big amounts of testosterone enter the body, homeostasis tries to put the things in order by triggering a stronger process of aromatization. This means that a big part of injected or swallowed testosterone is converted into estrogens, causing serious side effects like bitch tits, or also called gyno.

Each system has a different number of aromatase enzymes. The higher is their number, the bigger is the percentage of testosterone who get into estrogen. Thereby, persons with a big volume of aromatase enzymes can experience serious health issues even taking anabolic steroids even in smallest doses. Also, this group of bodybuilders has always to pay a bigger attention to antiestrogens drugs when going throughout a cycle.

Why Our System Has Such a Categorical Reaction to High Amounts Of Testosterone?

Normally a man body produces about 7 mg of testosterone per day. This is a quite modest dose, which not leads to massive muscle gains. Even try naturally, this level will increase but you will need to put in great efforts and much time on this. And efforts doesn’t mean to work hard in the gym only, but also to keep a close eye to your nutritional diet and rest time.

It is easier and convenient to get the testosterone level higher by taking steroids. Usually, one dose of steroid is at least 100 mg and higher. This means that suddenly high amounts of testosterone get into the body, causing a serious hormonal disbalance. Our body reacts and tries to keep a balance and begin to convert the surplus of testosterone into estrogen.

So, the answer is that our body is accustomed to a certain amount of testosterone produced daily. It always keeps a balance, that ’s why when big doses of synthetic testosterone enter the body it turns it into estrogens. Increased level of estrogen in the system has serious side effects that have to be carefully monitored.

Estrogen has not to be seen as something bad. It has very specific functions in the body like increasing the bone mass, improve libido and greatly add muscle mass if combined with testosterone steroid, for example. Estrogen is a natural steroid, which directly participates in the muscle building process.

Along with this, it makes the body to use glucose in a better way, which definitely reduce the recovery period. Being back in the gym as soon as possible and full of energy and with no soreness is the thing that every bodybuilder wants. And estrogen has a good influence on all this.


Antiestrogens Drugs:

Antiestrogens Drugs

- Arimidex (Anastrozole)

- Clomid (Clomiphene Citrate)

- Femara (Letrozole)

- HCG (Human Chorionic Gonadotropin)

- Nolvadex


But it has to be kept within normal limits. When it goes too high, serious side effects may occur as gynecomastia, weakness of immunity, and cholesterol issues. There are at least five types of antiestrogens recommended for use during post cycle therapy to reduce estrogenic activity in the body as mentioned in the table.

We can not say about these drugs that are very expensive as they were a few years ago when 1 mg pill of a brand name of Arimidex was sold with ten dollars. Nowadays the steroid market is much diversified, and you can find the same product at a very good price. Especially if you are not looking for brand names, and are ready to buy those produced by underground labs.

What are the Most Aromatizing Steroids?

Most Aromatizing Steroids

All steroids aromatase. This is the most important detail every person looking to get bigger have to bear in mind. But the way they do it differently in some degree. That’s why we can talk about most and less aromatizing steroids, but not about the concept of non-aromatization at all. Also, there are individual characteristics to the high number of aromatase enzymes in the body, which can turn a low aromatizing steroid into one very estrogenic.

Over the years of experience, it was observed that several anabolic steroids induce a greater estrogenic activity when area administered.

Top 4 Most Aromatizing Steroids:

  • Dianabol;
  • Anadrol;
  • Testosterone;
  • Deca

Both forms of Dbol, liquid, and pills, have a high estrogenic activity. The same thing can be said about esters of testosterone. It is tremendously to run a proper post cycle therapy with recommended antiestrogens when stacking two or more steroids from the above list. Do it because these steroids are in most cases associated with gyno development.

Water retention is in another unwanted side effects caused by aromatization. Water retention means that your body hold more water, making you look swallowed especially on the face area. Also, it causes in man fat deposition along the waist. The lower is estrogenic activity in the body while running a cycle, the less water your body retains. In other words, at the end of a steroid cycle, you will have more lean muscle mass gains, instead of such unwanted fat. Antiestrogens are of great importance in this case, so make sure you have them included in your steroid cycle plan.


ConsiderationsAromatization is the process during which the surplus of testosterone is turned into estrogens. It comes as a result of body tendency to keep an overall balance. Estrogen in normal limits is very beneficial for the body since it improves libido, increases bone mass and makes the muscles get bigger especially if mixed with a synthetic steroid like testosterone.

But when high amounts of testosterone enter the body, the estrogen level goes high too, causing serious health problems like gynecomastia, weak immunity, and cholesterol changes. Most of the bodybuilders want a non-aromatizing steroid at all, this being unreal. Since all steroids more or less are aromatizing.

So, the best would be mention low and high aromatizing steroids. The number of aromatase enzymes in the body has a great importance, the higher is their number the more testosterone into converted into estrogen. Thereby, even a low aromatizing steroid can be quite powerful for such a person.

    Yes, but i would suggest to add a testosterone enanthate or cypionate to this oral cycle , otherwise you will not see much effect from it . Don’t forget to add HCG and tamoxifen , to bring your bolls back to normal .

    Here is a good cycle:

    Week 1 – 12 testosterone Enanthate 500mg/Week
    Week 1 – 10 Nandrolone Decaonate 300mg/Week

    @ 300mg the Deca will help build strength and at the same time put some water in your joints. The Test level @ 500mg will def. help prevent the dreaded deca dick.
