Boldenone is a testosterone derivative, anabolic steroid. Its main actions are to build high-quality muscle mass and increase strength, increase body relief (in combination with the so-called "cutting"), increase the venous pattern, increase energy, improve well-being, increase self-esteem, and so on. 

The drug was originally developed to increase muscle mass in animals and was used exclusively in veterinary medicine. A little later, Boldenone's formula was studied in more detail and, as a result, it was recommended for use in people.  Its formula contains a double bond between the first carbon atoms. This contributed to the fact that the risk of side effects due to taking the drug is significantly small, and the variety of these effects is limited. 

The drug has good reviews, since its androgenic index is twice lower than testosterone, and the anabolic index is the same - one hundred, it has no estrogenic and no progestogenic activity, and, which is very important, is absolutely non-toxic to the liver. 

The drug is excreted from the body by the kidneys. The half-life is two weeks (or fourteen days). It is possible to detect the drug in the body almost six months after the last dose, since the Boldenone molecules can be completely excreted from the body four (in some cases up to ten) months after taking the last dose.

In addition, the drug gives stiffness to the muscles, improves vascularity. In terms of overall effects, it significantly increases appetite and red blood cell count, and promotes the release of erythropoietin in the kidneys as the result oxygen supply to tissues improves, but the blood thickens strongly, which can lead to thrombosis and problems with the cardiovascular system.

Boldenone is not subject to aromatization, does not activate estrogen receptors, has very minor androgenic properties and, unlike other steroids, can be used by persons with prostate diseases.

Bboldenone is also used in testosterone courses as an anabolic and a light aromatase inhibitor. In persons who are not subject to strong aromatization, boldenone may well replace the need for taking anastrazole.

Boldenone comes in undecelinate ester only.

Use to reduce estradiol

Boldenone – an anabolic steroid known for its anabolic qualities only, but also it is an excellent tool for reducing estradiol during the cycle. Boldenone has such a qualities as an increase in appetite and venousness on the body, but its main charm is that, along with the properties of an anabolic, it combines the properties of decreasing estradiol (female sex hormone). Usually, during steroid cycles, of professional athletes, the dosage of boldenone reach 800-1200 mg, which causes shock in newbies, who have never used it.

As an anabolic agent, this drug is not very effective, so its dosage should be quite high. Even if you are not a very heavy lifter, you will most likely not feel the dosage of 250 mg in any way, even if this is your first cycle. According to athletes, who used boldenone solo (without other drugs) after 4 weeks - the sensations were as if the athlete had completely dropped off the course, in addition, estradiol level felt below normal.

The conclusion is simple – boldenone can only be an addition to the main drugs in the cycle, but by no means its basis. During the cycle, testosterone must be included, otherwise you will lower your estradiol to unfavorable values for health. Boldenone is a drug that can be put only with testosterone together, to have an addition estradiol in your blood, which Boldenone decreases.

Otherwise, you will simply “kill” your estradiol with it. As you know, low estradiol leads to such consequences as reduced libido, osteoporosis, deterioration in mood, and others. The amount ratio of boldenone and testosterone should be individually selected.

  • Our recommendation is to start with 2 parts of testosterone to 1 part of boldenone.
  • Few days after your boldenone injection, check your blood estradol. If estradiol is still high, then you increase the dosage of boldenone.
  • Often the proportions of boldenone and testosterone can be 1:1 in order to keep estradiol in the middle of the reference values.
