Boldenone Undecylenate 1 ampoule/ml (250 mg/ml)


Boldenone undecylenate from ZPHC is a Dianabol molecule that is devoid of the 17-alpha-methyl group (this part of the molecule makes it possible for Dianabol to pass through the liver without being destroyed). If you compare the effectiveness of Boldenone undecylenate and Dianabol, then the results in mass gain and strength increase are almost the same.


Boldenone undecylenate (also known under the brand name Equipoise, Boldabol, Boldebal, Boldesten, Ganabol) is an anabolic steroid developed for use in veterinary medicine. The drug was created as a long-acting version of Methandrostenolone, but the result was a steroid that has completely different properties, despite the chemical similarity of the molecules.

Action of Boldenone undecylenate

  • A set of muscle mass. A slow but qualitative increase in muscle volume is observed. The nature of the effect is determined by the length of the ether: in the case of boldenone acetate or propionate, hypertrophy will occur much faster.
  • Increase in strength indicators. An effect that is almost always accompanied by an increase in the athlete's weight.
  • Increased appetite
  • Increase in erythrocyte blood mass. The drug stimulates the formation of red blood cells. Thus, the muscles receive more oxygen and can work more productively without the formation of lactic acid. The athlete's endurance increases.Boldenone is often used by track and field athletes, skiers and other endurance athletes.

Application of Boldenone (Course solo)

The course of Boldenone should be started only after a thorough medical examination and consultation with a doctor. Selection of the optimal dosage is carried out on the basis of previous experience in the use of anabolic and androgenic steroids, individual physiological characteristics and, in fact, the purpose of using this AAS. The average course of boldenone solo lasts from 8 to 10 weeks, 400-800 mg of the drug once a week for men, 50-100 mg for women. It is possible to start reception with a smaller dosage in order to feel the effect of the drug and take appropriate measures in case of side reactions.

Combined courses

As for taking Boldenone in combination with other AAS, Anavar and Winstrol are considered the best compounds for drying, Trenbolone and testosterone for mass-building courses. The latter combination significantly reduces the level of endogenous testosterone, and then the duration of the intake should be reduced to 6 weeks, plus antiestrogens should be included in the course. Two weeks after the course of Boldenone, PCT is performed, and boosters are taken for a month to restore testosterone secretion. Specialized sports nutrition helps to strengthen the effect of steroids.

Side effects

Many characteristics of Equipoise are determined by the presence of a double bond between the first and second carbon atoms. It significantly slows down aromatization. The steroid shows half the estrogenic activity compared to testosterone.Such side effects from Boldenone as an increase in blood pressure, edema and gynecomastia are practically not found even when the recommended dosages are significantly exceeded. Thus, there is no need to take anti-estrogens. A low level of androgenic influence allows women to use the steroid. Virilization occurs extremely rarely. The steroid is resistant to 5-alpha-reductase, and therefore practically does not cause androgenic manifestations in the form of baldness, prostate hypertrophy, acne, etc. When using the recommended dosages, the level of endogenous testosterone is slightly suppressed. If you know how to inject Boldenone correctly, then almost all negative reactions can be prevented.
