Information about the Drug

ULTRABOLDENONE 300 is a brand name for Boldenone Undecylenoate. It is powerful and safe and for beginners and for experienced users of sports pharmacology. Boldenone is an androgenic anabolic steroid with a good combination of anabolic and androgenic characteristics of 100/50 of pure testosterone. This is a mild medication that allows a person to gain weight stably and for a long time. The systematic administration of boldenone guarantees the athlete weight gain from 0.5 to 1 kg in 6-7 days. This is a pretty good indicator that will suit most athletes.

The use of this drug gives the user several major advantages such as: increase in muscle mass, increase endurance and increase strength.

Boldenone contains Undecylenoate ester, the eradication half-life of which is 8-9 days. During this time a constant concentration of the drug is maintained in the body of an athlete. This ensures a uniform effect throughout the entire cycle of use. The drug is perfectly combined with other anabolic steroids. This makes its use universal, since Boldenone can be used as the only one on the course as well as with heavier drugs.

Unlike many other products of this section of pharmacology, Boldenone Undecylenoate initially was used not in medicine, but in veterinary to gain weight in animals. Due to the fact that this drug was found to be absorbed and acting on the human body without  causing notable side effects in comparison with other anabolic steroids, boldnone started to be used in sport medicine.

Due to the fact that Boldenone has a great similarity with testosterone, it has the ability to accelerate metabolic processes in the body of an athlete similar to other anabolic steroids. Under the influence of this drug, there is a better absorption of nutrients, energy accumulation in the form of glycogen, burning of fat reserves, more abundant oxygenation of the body, and also increases the level of nitric oxide production. Taken together, these factors allow the athlete to train longer and more often. The recovery between workouts, including the healing of micro-injuries, also occurs more quickly.


Boldenone is usually used in the period of gaining muscle mass in bodybuilding, as well as to improve the basic characteristics of representatives of other sports.

Boldenone is not susceptible to aromatization. When it enters the bloodstream, its molecules are not converted to estrogens and therefore the athlete has fewer problems with side effects

The optimal dosage is selected based on previous experience with the use of anabolics, individual physiological characteristics and the purpose of using this drug.

The use of boldenone does not lead to rapid mass gain in a short time. Depending on the dosage, nutrition and training, the final effect may be different. When using the drug with a low-carb diet, you can expect a small set of only high-quality muscle, about 5 kg in a few weeks, but the gained mass will be dry, relief and with good venousness.

If the main goal is to gain a large amount of mass, you need to slightly increase the dose and establish a diet with a high-carb diet. In this case, you can gain up to 7-9 kg of total weight in 5 weeks.

In bodybuilding, dosages from 400 mg per week are used, this amount of the drug will significantly enhance strength and muscle gain. More experienced athletes use a dosage of 600-800 mg per week.

Injections are made every 7-10 days. The general course of application should not exceed 6-8 weeks, after which you should receive rehabilitation therapy.

Usually professional athletes do not take a course of boldenone solo. For more impressive results when gaining muscle mass, it is recommended to use boldenone in combination with various testosterone esters and / or Anapolon. In the course of drying, the best choice would be a combination with HGH or Winstrol.

With the combined use of anabolic steroids women should not take more than 50 mg of boldenone per week. When side effects appear, athletes should immediately stop taking the drug or reduce its dosage.

Side effects

The drug has a moderate androgenic index, this suggests that the manifestation of androgenic side effects is unlikely. But if you abuse this tool, the likelihood of their occurrence still remains. Regarding estrogenic manifestations, they are also unlikely to be with reasonable use, since the property of the drug to aromatization is also reduced.

The main side effects that may occur:

  • Androgenic (alopecia, coarseness of voice, acne, masculinization in women);
  • Estrogenic (gynecomastia, female-type fat accumulation);
  • Individual intolerance to the drug and its components.
  • Acne vulgaris, acne conglobata, seborrhea, stretch marks (due to rapid muscle enlargement), hypertrichosis (excessive body hair growth), androgenic alopecia (pattern hair loss; scalp baldness), fluid retention/edema.
  • Cardiovascular: dyslipidemia (e.g., increased LDL levels, decreased HDL levels, reduced apo-A1 levels), atherosclerosis, hypertension, left ventricular hypertrophy, cardiomyopathy, myocardial hypertrophy, polycythemia/erythrocytosis, arrhythmias, thrombosis
