The active ingredient present in BOLDO is Boldenone Undecylenate. 

It is not a fast mass builder, but BOLDO instead provides a slow but steady gain of strength and quality muscle mass, more defined and solid. There is no bloating effect, water is not retained in the muscle and the gained muscle mass will be retained after a finalized Boldenone cycle. The positive effects of BOLDO become most apparent when it is used for longer cycles, best effects are reached with min.16 weeks.

The well-balanced anabolic and androgenic properties of BOLDO are greatly appreciated by athletes, who generally consider it to be a stronger, slightly more androgenic, alternative to Deca-Durabolin.

BOLDO also increases the re blood cell production and leads to a higher hemoglobin level, what leads to a higher blood pressure and a high pump effect and strength and endurance for the training, enabling hard workouts. But athletes with naturally very high blood pressure levels should be careful regarding this effect, as a too high blood pressure might lead to negative cardiovascular side effects at a longterm use.

BOLDO is also a very versatile drug, and can be combined with a number of other agents depending on the desired result. 

For mass, it is commonly stacked with an injectable testosterone such as Enanthate or Cypionate. This should produce strong gains in muscle size and strength, without the same intensity of side effects of using testosterone (at a higher dose) alone. 

During a cutting phase, muscle hardness and density can be greatly improved when combining BOLDO with a non-aromatizable steroid such as Trenbolone Acetate or Methenolone Enanthate.

Although it stays active for a much longer time BOLDO is injected at least weekly for physique or performance-enhancing purposes.
