Why buy this product

Undecadrol by Balkan Pharmaceuticals is a long ester of the main male sex hormone Testosterone Undecanoate. It is used by bodybuilders and powerlifters to improve their athletic performance, build muscle and burn subcutaneous fat.

Testosterone undecanoate has the same properties as other esters of this hormone. Its main difference is that it is a "long" ester - after just the 1st injection, the steroid acts on an even hormonal background for 2 weeks, which is why it is often used during "eternal" courses.

  • anabolic activity index - 100%;

Effects of Testosterone Undecanoate

In the body, undecanoate is converted to dihydrotestosterone, the active metabolite of testosterone, which means that the substance is actually a prohormone.

  1. weight gain (given a well-planned diet);
  2. increased metabolic rate;
  3. protection of muscle tissue;
  4. reduces the risk of ischemia of the heart and coronary diseases;
  5. increases libido and potency (the opposite effect is possible);
  6. improves your strength;
  7. improves muscle relief;
  8. increases energy;
  9. faster regeneration;
  10. increase in collagen synthesis.

Application and dosage of Testosterone Undecanoate

It is necessary to administer the drug strictly intramuscularly - best of all in the gluteal muscle. The optimal course duration is 10 weeks, but with the addition of gonadotropin, its duration can be increased. Such a period of admission is due to the fact that the active substance accumulates in the body for a long time and is included in the work only 2-3 weeks after the start of administration.

Dosages of Testosterone Undecanoate depend on the weight of the athlete. Athletes weighing more than 80 kg should be administered 500 mg. If the athlete's weight is more than 90 kg, then 600-750 mg should be administered. Injections are made 1 time in 14 days - this is enough for a high concentration of the hormone in the body. After the course, you must pass the PCT.

With the correct dosages and the absence of individual intolerance to the active ingredient, the drug is not able to cause adverse reactions, otherwise the following deviations in the body's work are possible:

  • increased blood pressure;
  • excessive excitement, aggressiveness and irritability;
  • acne
  • excessive growth of hair on the body and baldness on the head.

These side effects are temporary and often disappear after stopping the steroid.
