Boldenone is the 1,2-dehydro derivative of testosterone and an anabolic steroid used in veterinary medicine . In Germany there are no approved finished medicinal products that contain boldenone.
How it works and abuse in sports
For some time now, Boldenone has been finding increasingly abusive use in bodybuilding . It is considered a doping agent .
Boldenone was developed in 1949 by the pharmaceutical company Ciba and is similar to Dianabol , only the lack of 17 α -alkylation in boldenone differentiates the two. Nevertheless, the effect of the two substances is completely opposite. Boldenone converts about 50 percent less to estrogen in the male body than testosterone. With simultaneous training, lean muscle building is possible without high fat and water content, which is why boldenone is mainly used in a diet or in athletes who primarily pursue high-quality muscle building. Furthermore, Boldenone strongly binds erythrocytes , i.e. red blood cells, which help the athlete to develop a noticeable vascularity .
Side effects
Common side effects are irregular resting heart rate , increase in blood pressure and worsening of blood lipid levels. Long-term use increases the risk of cardiovascular diseases enormously.
With higher doses, oily skin, acne and hair loss can occur. An often observed side effect is that from a dosage of around 400 mg (undecylenate) per week, the appetite can increase significantly. Estrogenic side effects are rare, as boldenone, as a testosterone derivative, can be aromatized, but only does so to a very limited extent and has a much weaker effect than testosterone on this point. An enlargement of the prostate can occur because boldenone is converted into dihydroboldenone by means of 5 α -reductase .
