Use in doping
The activity of boldenone is mainly anabolic, with a low androgenic potency. It has a very long half-life, with minimal blood levels present up to 8 weeks after discontinued use. Boldenone will increase nitrogen retention , protein synthesis , increases appetite and stimulates the release of Erythropoietin in the kidneys.The drug is commonly used in doping within bodybuilding, even though this use is illegal. If intended to assist in bodybuilding, the drug is taken as part of a steroid stack of other anabolic steroids, usually with a potent androgen like testosterone as the 'base' of the stack. Common bodybuilding doses range between 200mg to 400mg/week but could be as high as 800 mg /week. Boldenone has a low rate of aromatization ( about 50% of Testosterone ) , which means it does not convert to estrogen easily and does not cause very much water retention. Many Bodybuilders will find that it is a good replacement drug for Nandrolone .
Boldenone is among the substances banned by Major League Baseball, as well as most other major athletic organizations. As of November 2005, Matt Lawton is the only baseball player known to have tested positive for it. It is a poor drug of choice for any athlete who will be subject to a blood test due to it's long metabolic half-life. Trace amounts of the drug can easily be detected for months after discontinued use.
Boldenone has many of the common side effects associated with anabolic steroids. However, because it is not a very potent androgen, side effects are usually minimal. This is not a blanket-statement and depends on dosages and individual tolerances. Supression of the HPTA, water retention, possible increase in acne and possible conversion to estrogen , high blood pressure and DHT conversion are all side effects associated with Boldenone.
