Testosterone undecanoate. Combined course

Testosterone undecanoate is a powerful steroid that is widely used not only in medicine but also in sports, weightlifting, bodybuilding and other fields. The oral dosage form allows the athlete to cope without injections, which is appreciated not only by beginners but also by professionals with many years of experience.

Characteristics of oral testosterone undecanoate

The testosterone formula allows the active components of the drug to be absorbed through the intestinal mucosa. As a result, the male hormone does not enter the blood, but enters the lymph. This not only ensures good absorption, but also significantly reduces the toxic effect on the liver.

However, concomitant use of drugs that induce microsomal liver enzymes (barbiturates, rifampicin, carbamazepine, phenylbutazone, phenytoin) may decrease testosterone activity. This should be taken into account when prescribing the medicine.

Characteristics of oral testosterone undecanoate

The tablet version of Testosterone Undecanoate has been on the market for a long time, but this oral steroid is not the best option for creating and maintaining a high anabolic background. First of all, it is suitable for use in traditional medicine, not in sports. However, it is now quite easy to find Testosterone Undecanoate in injection form.

The main difference between anabolic esters and other testosterone esters is a long half-life. This indicator outperforms all other testosterone-containing AAS. On the one hand, this means that injections can rarely be performed. On the other hand, the potency of Nebido may be slightly lower than that of the same enanthate. This is because the ester residue occupies a fairly large percentage of the total amount of steroid in 1 ml. Testosterone Undecanoate is most often taken during HRT, which can last up to 4 months or more. In addition to the injectable versions of the undecanoate test, there are two oral versions: methyltestosterone and endoriol. Testosterone Undecanoate is also an oily ester and is actually no different in composition than its oral counterparts. The only difference is that the positive effects and side effects of this drug are less pronounced for a reason that will be discussed below. However, it stabilizes the androgen receptor no worse than injectable masters. The most common brand name for Testosterone Undecanoate is Nebido. That’s his name.


Since Andriol (oral version) is taken orally, it cannot bypass the liver. But 17-alpha alkylation for sites is not only a difficult task, but also with its presence (alkylation) the site does not undergo the required transformations. Simply put, Andriol cannot be converted to testosterone in this case. Therefore, it does not have a methyl radical at position 17 of its backbone.

To prevent its destruction by the liver, scientists have devised a very sophisticated mechanism. Andriol is available in the form of capsules containing an oily ether solution. Furthermore, its side chain differs significantly from the chains of other esters. Ideally (ie, in theory), this would make the drug lipophilic, allowing it to bypass the liver and enter the general bloodstream via the lymphatic system.

In theory, it’s great. But the drug received turned out to be insufficiently lipophilic or there were other problems that I am not aware of, but in practice this mechanism works poorly. The bioavailability of Andriol was found to be extremely low. So for all its effects (including side effects, remember) it’s inferior to its counterparts and to men over thirty it’s an elephant pill. But it can be useful for young athletes who have just decided to get acquainted with the rich world of sports pharmacology.

And the last. In addition to Andriol, there is also the injectable paste Aster Andenknot (Nebido). In practice, it is similar to testosterone enanthate. Except for a longer half-life, which must be calibrated within 10-11 days.

Weight gain

Young and fresh bodybuilders can start their knowledge of testosterone with Nebido. An excellent androgenic course base for an organism not drenched in matter. It also does not promise side effects.

Dry off

Perhaps the only version of Testosterone that doesn’t retain water and marbles in microscopic amounts. In other words, it will perfectly complement the typical speakers of this era. Of course, it doesn’t protect meat like Testosterone Propionate does (for example). But the risk is zero.

Steroid addicts

It is not strange, but this drug can be useful for true steroid fans. It perfectly stimulates sexual desire. Therefore, it helps in the periods of forced pauses between the long routes and the so-called “gangways”.

However, all of this only applies to the use of Testosterone Undecanoate without the use of additional drugs. And by using them, you can greatly enhance the effects of Testosterone Undecanoate use.

How to increase the effectiveness of the drug?

Testosterone undecanoate is often combined with other drugs to increase its effects. This solves many of the problems that athletes face when taking a substance to increase muscle mass, build bones and increase strength.

In order for testosterone to work effectively and contribute to a wide range of muscle mass, it must be combined with nandrolone. This combination is the most effective and does not cause side effects for the body. In this case, the standard dose of the drug can reach 240 mg per day.

How to increase the effectiveness of the drug?

Testosterone undecanoate works great with most steroids. Winstrol will be the best combination option for increasing muscle mass. It is also effective to use the medicine with a pack of books that replace Dianabolt with Andriol during the course. This combination of drugs is completely safe for the body and is ideal for beginners and athletes who care about their own health.

Andriol and Winstrol course

A typical course of testosterone undecanoate produced under the Andriol brand lasts 7 weeks.

Athletes often start using Andriol, which already has problems with flavoring drugs in previous classes. The package leaflet contains the necessary information to avoid side effects if you take large amounts of the medicine. It is enough to take about 240 milligrams during the day. You can do this once in the morning or in two or three divided outlets.
