Testosterone Undecanoate is a natural testosterone ester. Unlike the more common sports hormone esters, it is available in oral (tablets or capsules for oral use) and injectable (solution for injection) forms.
Testosterone Undecanoate Description
Naturally, the steroid Testosterone Undecanoate is characterized by strong androgenic and moderately weak anabolic activity. In other words, it is primarily an androgenic steroid hormone. It has no long-term effect, therefore, regardless of the form of release, it requires intensive use: the maximum concentration in the blood is recorded ≈ 2-6 hours after ingestion / injection.
In the body, testosterone undecanoate is converted to dihydrotestosterone (an active metabolite of testosterone), which has the main biological effect: promotes the development of male genitals and secondary male sexual characteristics, weight gain, increased efficiency, increased strength and endurance, accelerates recovery, even increase user libido. Since dihydrotestosterone does not aromatize, it does not cause an increase in estrogenic activity, therefore it does not cause the formation of estrogen-dependent side effects such as fat accumulation in women, fluid accumulation and gynecomastia in men.
At the same time, testosterone undecanoate, produced in the form of both tablets and injections, remains a safe (non-toxic) drug for the liver. This is especially true for the oral form, which after ingestion is absorbed through the digestive tract into the lymph instead of into the bloodstream, thereby bypassing the user’s liver.
You might think that Testosterone Undecanoate is an ideal steroid in terms of effectiveness and safety. But practice shows that this is a wrong assumption. In fact, the benefits of the substance are offset by its minimal bioavailability of ≈ 7%. For the development of a pronounced effect, it is necessary to use a high dose, which is associated with the risk of androgenic side effects: acne, oily skin, increased aggression, irritability, priapism, oligospermia, prostate enlargement, hair growth. and, on the contrary. , baldness
Testosterone undecanoate course
The average doses of Testosterone Undecanoate recommended for athletes range from 40 to 240 mg per day: they are at least 40 mg per day, otherwise they are ineffective but do not exceed 240 mg per day, otherwise they are dangerous. As a drug and doping substance, it does not tolerate abuse. This is especially important to remember for women, where testosterone products are capable of causing androgen-mediated virilization, a male syndrome accompanied by rash, swelling of the voice, increased aggression, excitability, alopecia and even menstrual irregularities.
To develop to the maximum in the sports field, a combined regimen of Testosterone Undecanoate is necessary. Only in a safe dose does the steroid not have high effectiveness, but reveals its potential in analogues: it is effectively combined, for example with turinabol, boldenone undecylenate, methenolone enanthate, methandienone or nandrolone decanoate.
Like most of the pharmacology in demand today 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 eunuchoidism in adult men.
Athletes do not take testosterone undecanoate for its intended purpose, therefore it is recommended to consult a specialist in advance for instructions and to be examined to rule out contraindications: tumors of the mammary glands, prostate and testicles – for men; pregnancy and lactation – for women; children’s age and hypersensitivity – for both sexes.
