Boldenone available as the Undecylenate ester is an anabolic steroid developed initially for veterinary use, mostly for treatment of horses. It is derivate of Testosterone and exhibits strong anabolic and moderately androgenic properties. Boldenone Undecylenate increases nitrogen retention, increases appetite and stimulates the release of erythropoietin in the kidneys. It has a very long half-life, and can show up on a steroid test for up to 1.5 years, due to the long Undecylenate ester attached to the parent steroid. Trace amounts of the drug can easily be detected for months after discontinued use.
Bodybuilders and athletes that use Boldenone Undecylenate accomplish the result of very defined and solid muscular struture. It is often used in cutting phases, to improve density and hardness of the muscles. Boldenone Undecylenate gives higher quality gains in muscles than taking a steroid based on Testosterone. Usually Boldenolone is compared with Nandrolone, but water retention with this product would be slightly higher than that with Nandrolone Decanoate, but less than with Testosterone. The toxicity to the liver of this compound is quite low and manifests itself only in high doses. It is important to know that Boldenone Undecylenate steroids are not a rapid mass builder, but they provide a slow but steady gain of strength and quality muscle mass. The most positive effects of this drug are seen when it is used for longer cycles, usually lasting at least 10 weeks in length.
As a stack: in cutting phases, to maintain and to improve the hardness and density of the muscles it is advised to combine Boldenone Undecylenate with non-aromatizable steroids such as Trenbolone Acetate, Fluoxymesterone, or Stanozolol. A combination of Human Chorionic Gonadotropin and Clomiphene Citrate/Tamoxifen Citrate may likewise be needed at the conclusion of each cycle to avoid a crash, especially after long duration cycles.
