Chemical structure

Chemically, Boldenone is a synthetic analogue of testosterone, in which the first and second carbon atoms are linked. It is important to note that the activity of the drug is approximately two times less than that of testosterone.

Very often, boldenog is compared with a drug called nandrolone. However, such comparisons can hardly be called justified: drugs have a different mechanism of action on the human body. Boldenone is much more like testosterone than nandrolone.

It is important to note that the drug is available in various forms, which act in the same way. The main difference is the period during which the compound is metabolized by the human body.

Steroid profile

The drug has the following effects:

  • anabolic - completely similar to testosterone;
  • androgenic - the drug is two times weaker than testosterone;
  • estrogenic - moderate effect;
  • progestogen - extremely low exposure.

The drug does not have any effect on the functioning of the liver.

What are the effects of boldenone "> How to take boldenone?

You can take Boldenone only after undergoing a complete medical examination. The dosage is selected depending on what preparations the athlete took before and how his body reacted to them. The individual characteristics of the body and the goals with which Boldenone will be taken are also important.

As a rule, the course of admission lasts from eight to ten weeks. At the same time, men take up to 800 mg of the drug per week, and women take up to 100 mg. It is important to start with a small dosage to check how the drug affects the body. In addition, it will help to track in time all possible adverse reactions.

What can the drug be combined with "> Winstrol and Anavar (if the athlete is drying) or Trenbolone (when taking the course of gaining body weight). If the drug is taken simultaneously with testosterone, then the male hormone begins to be produced in the athlete's body in a smaller volume, so the course is required reduce to two months.To reduce possible side effects, antiestrogens should be taken at the same time as boldenone and testosterone.

Two weeks after the course of taking the drug comes to an end, you need to use boosters for three to four weeks: this will help bring the level of endogenous testosterone back to normal.

To enhance the effect of the drug, it is necessary to choose high-quality sports nutrition.

The most popular combinations with boldenone are the following:

  • during mass collection: up to 250 mg of boldenone in combination with testosterone enanthate. This combination is considered the most successful for those who are just starting their journey in sports. In the first two months, you need to take 800 mg of Equipoise and 500 mg of testosterone enanthate every week. At the tenth week of the course, Anastrozole is turned on (half a tablet once every two days). From the eleventh to fourteenth week, you need to take 20 mg of Tamoxifen daily. In the last week of the course, the volume of Tamoxifen should be reduced to 10 mg;
  • on drying, Boldenone is combined with testosterone propionate and Winistrol (200 mg, 100 mg and 50 mg, respectively). Vinistrol, which is included in the course after two to three months, allows you to gain high-quality muscle volume.

What are the side effects of the drug?

Due to the fact that the first and second carbon atoms in the preparation are interconnected by a strong bond, Boldenone is absorbed quite slowly. The drug is about half as active as regular testosterone. Therefore, such side effects as hypertension, the appearance of puffiness and an increase in breast size are almost never found even if the athlete risked exceeding the recommended dosage of the drug. In addition, there is no need to take antiestrogen drugs.

Due to the characteristics of the effect on the body, boldenone can be taken by women: viralization from systematic administration is practically not expressed. There is no baldness, the appearance of acne, prostate hypertrophy and other unpleasant symptoms. Of course, the absence of side effects is possible only if the recommended dosages are not exceeded.


Most athletes who took Boldenone noted a qualitative increase in muscle mass, as well as a marked increase in strength indicators. Reviews suggest that the drug is very effective both in solo administration and in various combinations. Trainers often recommend boldenone as the first drug that has androgenic and anabolic effects.

Athletes in their reviews note that the drug is effective and does not have side effects if taken in the recommended dosage. In rare cases, there are negative side effects that are caused by the fact that boldenone was consumed in a larger volume than recommended by the doctor.

True, the drug has one drawback: its rather impressive price. Therefore, many athletes prefer more affordable drugs with a similar effect on the body.
