The pros and cons of Boldenone

Boldenone is a steroid, which was originally developed for use in human and veterinary medicine, but in recent years it has been often used in sports. The drug is similar in composition to testosterone, but affects the human body differently.


Its main feature is  the positive effect on  the metabolic processes in the body, especially the protein synthesis in muscle mass, which in fact is most important for athletes.


Positive Effects of Boldenone :


The main effects of Boldenone :


● The drug  allows the athlete to build quality mass, slowly but surely.

● It increases the appetite, which is important for athletes. This is also the reason why it is used in livestock breeding also.

● Improves strength and endurance in athletes.

Boldenone increases the number of red blood cells and thereby improves the oxygen supply to the muscle tissue.

●  Normalizes metabolism.

● Improves the muscle protein synthesis.


Side Effects of Boldenone :

Boldenone is one of the least toxic anabolic steroids. It does not affect the liver.


The drug has moderate androgenic effects, so such events as baldness, acne, and prostatic hypertrophy are rarely viewed. Also this fact allows the drug to be used by women, since most anabolic steroids have strong androgenic activity, and therefore most of them are not recommended for admission by women.



Estrogenic activity or growth of the mammary gland are virtually undetectable, even with quite an impressive dose of the drug.


The drug has an effect on the cardiovascular system, mainly due to increased cholesterol levels, but this effect is much less pronounced. While taking any anabolic steroid, it is recommended taking fish oil at a dose of four grams per day. Also it is recommended to reduce the consumption of simple carbohydrates and saturated fats.


If we talk about steroid profile, compared with Boldenone, Testosterone has 50% more androgenic effect and more impact on the liver.


How to take Boldenone ?

The administration of the drug may be done individually and in combination with other steroids. For individual reception, the recommended dose is one injection per week, in the amount of 400-800 mg.


A larger dose is considered ineffective and increases the risk of side effects significantly. A cycle with Boldenone lasts 8-10 weeks.



After completing the course it is recommended to take anti-estrogens, which help minimize the side effects of steroids - PCT (post cycle therapy). For  achieving best results, it must be combined with effective training and sports nutrition.

 If you plan to combine Boldenone with other steroids, such as Testosterone Enanthate, the steroid cycle should be reduced to six weeks.


Steroid combinations whit Boldenone

A know combination is Boldenone + Testosterone Enanthate, you can add Tamoxifen or Proviron to the course.


This combination is known for being the best for beginner bodybuilders, because Boldenone suppresses estrogen activity and increases the anabolic activity. This cycle is designed  for longer term. From the first to the eighth week, the intake should be : injections of testosterone enanthate 500-800 mg per week and Boldenone of 200-400 mg per week. On the tenth week add Proviron or Tamoxifen  and take to the eleventh.


Here we will describe an efficient cycle for raising clean and quality muscle mass :


● Winstrol + Boldenone and Testosterone Propionate. The proportions of Winstrol are 50 mg (oral) up to 6 weeks in the course. Boldenone at a dose of 200 mg and Testosterone at a dose of 200 mg. This applies from the 1st to the 10th week (beginning to end).


● For women, the doses of the 1drug must be much lower than in men, in the range of 50-75 mg weekly. Despite being one of the few drugs that can be taken by women - it should be used carefully. The drug has a sustained action, which does not allows you to control the level of hormones in the blood and can lead to masculine effects can with time.


● Boldenone is often used to replace the initial cycle  with boldenone especially in those sports where the athletes need endurance. The unique function of the drug is in the release of erythropoietin in the kidneys, which leads to an increase in red blood cells. It is also ideal steroid at a time of relief, as it does not cause water retention in the muscle tissue.


● The athletes give positive reviews on Boldenone (intense action, muscle quality, without side effects, affordable, and so on). The drug won more than 80% of positive opinions of athletes who have benefited from its help.


History of medicine

As an anabolic steroid, Boldenone was first developed in 1949 by the pharmaceutical company - Ciba. In the 50's and 60's, it was put up for sale under the name Parenabol. It main purpose was  the treatment of osteoporosis and other diseases of the musculoskeletal system. But was quickly pulled off from the market and was banned in 1970. Its use was only allowed in veterinary medicine, mostly for horses.



The molecular structure of the two steroids is almost identical, except for the methyl group at position 17. However, exactly this difference plays an important role in changing the structure of the molecule. Methandrostenolone methyl group increases the incidence of side effects, especially to the liver. Methandrostenolone is also not able to activate the androgen receptor, thereby significantly inferior to Boldenone.The identical effect is an increase in appetite, which is desirable in bodybuilding.



Boldenone is considered a lighter version of testosterone, since the drug lacks the enzyme 5-a reductase, which is the main difference. As a drug, it is a stabilized androgen receptor and has non-genomic activity.



Despite the disparity of the molecular structure of  the drugs, they are identical in properties. In some cases they are applied interchangeably as steroids. The difference between them is that the non-genomic activity is more pronounced in progestogen action of Nandrolone, allowing it to build muscle mass faster.


Side Effects

Despite the fact that the drug is light and there is almost no negative impact on the body, it still remains a steroid, which requires certain rules in order to avoid side reactions. Here are the main ones, which also relate to the intake of other anabolic steroids:


● Adjust the dose of the drug, do not exceed the recommended

● The cycle time should not exceed 12-16 weeks.

● Have regular blood checkups for biochemical and hormonal analysis

● Intake of an anti-estrogen in order to control testosterone production and prevent gynecomastia (growth of mammary glands).
