Understanding and Differentiating EstersTop-Steroids-Online
Trenbolone Acetate, Trenbolone Enanthate, Testosterone Cypionate, Testosterone Propionate...
But what are these names that follow molecules? Does this have an influence on the way to take my products?
The answer is YES: the name of theester is very important for the construction of your cure.
One of the most misunderstood topics in the steroid world is theester : i.e. the mechanism by which steroids such as testosterone cypionate, testosterone enanthate, and esterified injectable Sustanon or Trenbolone enanthate or acetate work in your body.
If you take a look on the internet, you will no doubt find countless articles which consider one form of a steroid to be much more effective than another.
Arguments about the superiority of cypionate over Enanthate or even Sustanon over all other testosterones are, of course, very common but are misconceptions.
Indeed, each ester has its particularity and, used intelligently in your treatment, it will be your perfect ally to obtain the results you desire.
What is an Ester?
Take the example of testosterone which comes in different esters : cypionate, enanthate, propionate, heptylate, caproate, phenylpropionate, isocaproate, decanoate, acetate… the list goes on and on.
In all of these examples, the “parent” hormone is testosterone, which has been modified by adding an ester to its structure.
The following question then arises: What is the difference between the different “esterified” versions of testosterone in terms of their use?
It is simply a question of the speed of assimilation of the molecule by the organism.
In chemistry, the function ester denotes a characteristic group formed from an atom linked simultaneously to an oxygen atom by a double bond.
This chain is usually attached to the steroid hormone at the 17 carbon position (beta orientation).
The esterification of a anabolic steroid / injectable androgen essentially accomplishes one thing, it slows down the release of the active substance of the molecule from the injection site.
This happens because theester in particular will have lowered the solubility in water or oil containing the steroid.
This will have the effect of forming a deposit in the muscle tissue, from which circulation will pass slowly and the steroid will be taken up in small amounts by the blood.
Generally, the more soluble the ester chain, the faster the hormone will be released.
The slowing of the release of the hormone is a great advantage in a cure. This is because without an added ester, free testosterone (or other steroid hormones) would only remain active in the body for a very short period of time (usually a few hours). It would therefore require a heavy and unpleasant daily injection schedule if one wanted to maintain a high and stable level of testosterone in the body.
With the addition of an ester, the athlete can therefore reduce the frequency of injections.
Adding an ester thus amounts to providing users with ease of use by making the treatment much less restrictive.
Is one ester stronger than another?
A bit of technique now.
We have therefore seen that esterification temporarily deactivates the steroid molecule and thus allows assimilation by the organism better distributed over time.
With a blocking chain in the 17 beta position, binding to the androgen receptor is not possible, so it cannot exert any activity in the body.
In order for the compound to become active, theester must therefore first be removed (its solubility explained in the previous chapter). This happens automatically once the compound has filtered into the bloodstream.
This will restore the hydroxyl (OH) group to the 17 beta position, which will cause the steroid to bind to the appropriate receptor.
It is therefore after the disappearance of the ester that the steroid is able to have an effect on the skeletal muscle tissue.
You are already beginning to understand why it is nonsense to consider Cypionate to be stronger than enanthate. This is because your muscles only distinguish free testosterone, no matter which ester was used for the administration of the molecule.
There are many different esters that are used with anabolic steroids but again, they all do the same thing: reduce solubility.
A ester as Propionate for example will slow the release of a steroid for a few days, while the slowdown will be several weeks with a decanoate ester.
Esters therefore have no effect on the estrogen or DHT (dihydrotestosterone) aromatization tendency of a steroid or on the overall potency of the compound.
The differences in results and side effects that can be noticed by bodybuilders who have used different esterified versions of the same basic steroid are just matters of timing.
For example, Enanthate will cause estrogen related problems more easily than Sustanon, quite simply because Testosterone Enanthate levels will have their peaks and troughs much sooner (1 to 2 weeks for enanthate versus 3 to 4 weeks for Sustanon).
The same is true for testosterone suspension, which is probably the most conducive to developing side effects quickly. Simply because the hormone levels in the blood peak very quickly with this steroid. Instead of waiting weeks for testosterone levels to rise to their highest point, here we are, for the slowest, at 2 days.
Considering an equal testosterone blood level, there would be no difference in the aromatization conversion rate or DHT between the different esters. It's just the speed of this mechanism that differs.
The different ester profiles in detail.
Now that we know what an ester is and how it works, we'll break down the most popular ones in alphabetical order. This will help you to better control and optimize your cures and thus obtain better results.
C2H4O2 chemical structure.
We also talk about acetic acid. Acetate Ester delays the release of a steroid for only a few days. Contrary to what you may have read, acetate esters do not increase the tendency for fat removal. Again, there is no known mechanism that allows acetate to burn fat.
This ester is used on Primobolan (metenolone acetate) oral tablets, on Finaplix (trenbolone acetate - “Tren A”) and occasionally for testosterone.
Chemical structure C8H14O2.
Cypionate is a very popular ester in the United States. Its duration of release is almost identical to enanthate (10-14 days). In the US, athletes generally think that cypionate is more potent than enanthate. Yet there is very little difference between the two. The Enanthate ester is actually slightly smaller than cypionate, so it releases a tiny (maybe a few milligrams) amount of steroids more when compared.
Chemical structure C10H20O2.
We also talk about decanoic acid. The decanoate ester is most often used with nandrolone (as in Deca-Durabolin). It is present in virtually every corner of the world. Testosterone decanoate is also the longest active constituent in Sustanon, greatly extending its release time. The release time with decanoate compounds is barely less than a month. However, it was recently found that the levels seem to drop significantly after two weeks. To keep blood levels more uniform, athletes will follow a weekly injection schedule.
Chemical structure C7H14O2.
It is one of the most important esters used in the manufacture of steroids, most commonly seen with testosterone. It is also used in other compounds such as Primobolan Depot.
The enanthate will maintain a balanced level of the hormone for about 10 to 14 days.
Although enanthate compounds are often injected as part of medicine on a monthly or even bi-weekly basis, athletes, on the other hand, will prefer weekly or bi-weekly injections to help maintain a consistent testosterone level.
Chemical structure C6H12O2.
This esters has a slightly shorter lifespan than enanthate and is only used with testosterone in “blends” of the Sustanon or Omnadren type.
Chemical structure C9H10O2.
The phenylpropionate ester will prolong the release of the active steroid for a few days longer than the propionate ester.
To maintain propionate-like blood levels, injections are given at least twice a week. Deca-Durabolin is the most commonly seen product with a phenylpropionate ester (nandrolone phenylpropionate - "npp") but it is also used with testosterone in Sustanon and Omnadren.
C3H6O2 chemical structure.
Also called Carboxyethane or propionic acid. The propionate ester will slow the release of a steroid for several days.
To allow blood levels to rise rapidly, the propionate compounds are usually injected two to three times per week. One of the most well-known steroids is testosterone propionate.
Chemical structure C11H22O2.
Undecanoate is not a very common ester. It only appears to be used in the preparation of nandrolone (Dynabolan) and oral testosterone undecanoate (Andriol). Since this ester is chemically very similar to undecylenate (There are only two more hydrogen atoms), it has a similar release time (About 2-3 weeks).
There is no reason to believe that it has any unique properties compared to other esters because it is used in the oral preparation Andriol.
Andriol actually works very poorly to supply testosterone, reinforcing the idea that oral administration really isn't the ideal use of esterified testosterone.
Chemical structure C11H20O2.
This ester is very similar to decanoate, containing just one more carbon atom. Its release time is also very similar (around 2-3 weeks), possibly extending a day or two longer than decanoate.
Undecylenate seems to be exclusively reserved for the veterinary preparation Equipoise (boldenone Undecylenate), Equipoise works very well for athletes.
Again, weekly injections are the most common.
Each ester therefore has its particularity concerning the release of the hormone in the body. But this release time is also dependent on another factor, a technical factor: the weight of theester.
The more the chainester will be long the heavier it will be. In the case of testosterone enanthate for example, 250 mg of esterified steroid (Testosterone enanthate) is equal to only 180 mg of free testosterone per 70 mg of enanthate.
You will understand, propionate being the shortest ester, it is therefore this esters which is the lightest.
So although the advent of esters is a valuable advance in the steroid field, they do not alter the anabolic potency of the steroid in any way.
Testosterone remains testosterone, trenbolone rest of the trenbolone, etc…. Some will claim that a form ofester of this or that hormone is much better than another: it is a totally unfounded and erroneous view.
