Testosterone undecanoate. Solo course

Testosterone undecanoate is a fatty acid ester of natural androgenic testosterone. In the human body, it is converted primarily into dihydrotestosterone, a metabolite of testosterone. This makes it an effective tool in the treatment of various diseases. The pharmacological action of the drug contributes to the absorption and improvement of muscle mass.

The device is ideal for easy muscle building, drying and strength training. Testosterone undecanoate is actively used by powerlifters, powerlifters, powerlifters and bodybuilders in classes.

Very often, a substance is used alone orally, without being combined with other medicines. The ease of use and the ability to refrain from injections make Testosterone Undecanoate tablets and capsules particularly appealing to beginners.

As a remedy and medicine, it does not forgive abuse. This is important to keep in mind, especially for women in whom testosterone products can cause androgen-mediated viralization, viral syndrome with skin rashes, voice crystallization, increased aggressiveness, arousal, hair loss, and even menstrual irregularities.

A combined cycle of Testosterone Undecanoate is necessary to make maximum progress towards athletic goals. Only in a safe dose, the steroid does not have a high potency, but it shows its potential in combination with analogs: it is effectively combined with, for example, Turinbol, Boldone Undecylanate, Methanol Nanthate, Methandinone or Nandrolone Decanoate.

Like most pharmacology currently in demand in sports, oral and injectable testosterone undecanoate was not originally developed for sports but for medical use: for indications ranging from the treatment of hypopituitarism in adolescents to the treatment of eunuchs in the elderly.

Athletes do not take testosterone undecanoate for its intended purpose, therefore it is recommended to consult a specialist in advance for advice and tests to exclude contraindications: tumors of the breast, prostate and testicles, for men; Pregnancy and lactation – for women; Age and hypersensitivity of children – to both sexes.

The drug alone

The route of administration and dosing regimen of testosterone undecanoate will depend on a number of factors, including the dosage form of the drug and the age of the user. It is best to ask your doctor to determine the optimal dose. In this case, strict compliance with the dosage form of a particular medicinal product, as well as the instructions for use and the dosing regimen, must be strictly observed.

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 due to the fact that the ester residue occupies a fairly large percentage of the total amount of steroid in 1 ml.

The recommended dose of testosterone undecanoate for athletes is 40-240 mg per day. Beginners are advised to start taking the medicine at 40 mg daily. It is useless to take less, because the concentration of active ingredient will not be enough and such a treatment will be ineffective. In addition, the daily dose is gradually adjusted to 240 mg, but do not exceed it, as this can be dangerous.

After oral administration, 45-48% of the active substance is absorbed from the small intestine. The maximum concentration in the body is reached 2.5-5 hours after a single dose. In the skin, prostate, seminal vesicles and epididymis, the drug is converted to 5-alpha-dihydrotestosterone by the enzyme 5-alpha-reductase.

The half-life is about 3-4 hours and is excreted mainly in the urine as metabolites (glucuronides and sulphates). In the first 24 hours, I get about 40%, and in a week – 50-70%. A small amount of the active substance is excreted in the faeces.

In fact, the drug is completely safe. However, this applies to male athletes. Online reviews of the drug suggest that women should not use it. This is due to a decrease in estrogen levels in the body.

The steroid can cause an increase in blood pressure, the development of hypersexuality, and an increase in water retention in the body. Taking Andriol can lead to increased erection in men. There is no information on other side effects.


As a drug and doping agent, it does not tolerate abuse. This is especially important for women in whom testosterone products can cause androgen-induced virilization – a male syndrome with rash, harsh voice, increased aggression, irritability, alopecia and even menstrual disorders.
