Anabolic Esters: What They Are, What They Are For and How They Work!

Reading Time: 5 minutes

If you are a bodybuilder and use anabolic steroids, you must have heard about anabolic steroids. esters shorter or longer esters, right? But do you know what these esters are? What is his role? What are worth for?

Speaking briefly, the esters are responsible for modifying the half-life of anabolic steroids. That is, the action time of the anabolic inside your body. Some of them are the decanoate, enanthate, cypionate, among several others.

In this article I will explain better their function and how they work so you know how to choose the best ester for your cycle.

Esters: What are they?

Esters are organic compounds widely used in organic chemistry and biochemistry, being a product derived from the reaction of an oxyacid with a phenolTo alcoholTo enol or a heteroarenol.

mixing ester anabolic salts

This reaction releases water and its hydrogen is formed by the acid of the first with the hydroxyl group of the second.

This acid can still be a carboxylic acid, where there are some changes in the ester formation reactions, but which are based on the same principles mentioned.

Esters have several applications, however in this article, we will focus on their uses in conjunction with the anabolic steroids!

Esters and the half-life

We can say that an anabolic half-life is the time of action it has on your body (this does not mean detection time through examinations).

This information is useful insofar as we are able to manipulate the ways to keep the concentrations always stable in the body, making its effects continuous.

Imagine that you use a medication that should be used every 6 hours. This means that after 6 am your activity is little or nil and, therefore, its effects are no longer efficient.

Thus, you need this periodic intake, that is, every 6 hours, so that it is always active in your body.

So the function of the ester for the anabolic is basically this: control the time of action that a certain anabolic has on your body. Short esters, means that that anabolic's action time is short, long esters, means that that anabolic's action time is longer.

A final point to be considered when it comes to half-life is that it does not mean the detection time of the anabolic steroid in the body. For example, the anabolic can have a half-life of 12 hours, but it can be detected by exams up to 6 months.

Can esters influence the effects of anabolic steroids?

We know that Testosterone it's just a molecule. However, it can be bonded with some esters, such as cypionate or propionate.

Theoretically, we know that esters do not perform functions that can bring about changes in the effects of the molecule itself. But in practice, they can cause some differences to be big.

Esters vary in their ability to reduce the water solubility of a substance. steroid. Thus, the more insoluble it is, the longer its half-life.

Therefore, it is possible to explain why propionate only preserves the half-life of testosterone in much less time than an enanthate or decanoate ester. They can also influence the ability and time to convert that steroid into DHT.

Os levels of flavoring can also be observed with different esters. For example: It is known that the faster the maximum testosterone peak is reached, the greater the aromatization. With that in mind, the prolonged use of anabolic steroids with shorter esters can be highly harmful.

However, with longer esters we can make these peaks occur later and, therefore, they can often be more suitable. Short esters are normally used for short periods only.

Despite this, the axle suppression brought by anabolics with longer half-lives are considerable, especially since even after stopping use, they will still be active in your body.

Longer esters typically cause higher rates of fluid retentionusually due to suppression of hormonal changes resulting from the cycle. However, this is still very controversial and should take into account individual factors, such as time of exposure to the substances, dosages used and substances used as well.

The heavier the ester chain, the higher its total percentage. For example, in the case of Testosterone 250mg of cypionate means just 180mg of free testosterone. Enanthate, on the other hand, would have, in the same dosage, a little more free testosterone, which would also be higher than that of propionate.

That is why cycles with longer esters usually require higher dosages than cycles with shorter esters.

Main characteristics of the main esters

After going deeply into the main concepts of esters and their advantages and disadvantages, it is time to learn a little about each one specifically. Come on?

  • Acetate

Referred to acetic acid, and has a relatively short half-life of a few days. It can be used with anabolic steroids, such as trenbolone, testosterone and the primobolan.

  • Propionate

Regarding carboxyethane, it has a short half-life, usually drugs that carry this ester need to be used more frequently (every 2 days, for example), in order to maintain the most stable concentrations in the body.

  • Phenylpropionate

Ester referred to phenyl propionic acid, with a short half-life, normally anabolic steroids that take it, should be administered twice a week.

  • Isocarpoate

Regarding isocarpoic acid, its half-life is relatively short, lasting approximately one week.

  • Carpoate

Referring to hexanoic acid, it has characteristics almost the same as isocarpoate, having a relatively short half-life and lasting approximately one week.

  • Enanthate

Regarding heptanoic acid, it is one of the best known and most pronounced esters among anabolic steroids. It has a half-life of 10-14 days. It is typically used with substances such as testosterone and trenbolone.

  • Cypionate

Being one of the longest commercial esters, normally its main application is with testosterone. It has a half-life of approximately 14 days.

  • Decanoate

Regarding decanoic acid, its main application is with nandrolone, but it is also used with testosterone. Its half-life is about 14 days and its administrations are usually weekly.

  • Undecylinate

Referring to undecylenic acid, it is very close to decanoate and contains only one more carbon atom. It can last up to 21 days in the body. Its main application is with the Boldenone.

all about anabolic steroid esters

Obviously, there are several other esters, however, these are the most applicable today and most used in the world of anabolic steroids.


Esters substances that make it possible to control the half-life of an anabolic, making it able to show better results in the body and, at the same time, reduce the collateral effects and undesirable.

Understanding how esters work and understanding the changes they cause in substances is essential to properly handle a cycle according to your goals.

However, if you still want a deeper knowledge, not only about ester, but about steroids anabolic steroids in yes, I suggest you get to know the Formula dos Gigantes program.

Good cycles!
