Description

What is boldenone used for?
There is no therapeutic or medical use for boldenone in humans. More specifically, it is not approved by the Food and Drug Administration (FDA) for use in humans for any reason.

In addition to being illegally sold and used for human performance enhancement, boldenone is used illegally in racehorses to enhance performance, despite being banned for use in horses competing in Olympic and Paralympic events. On an international and agricultural level, boldenone is also largely illegal for use as a growth promotor in farm animals, and most countries have surveillance programs that test for boldenone in animals raised for food production.

Is boldenone prohibited in sport?

Yes, boldenone is prohibited at all times for all athletes, including elite, recreational, Masters, and junior level athletes. Boldenone is classified on the World Anti-Doping Agency (WADA) Prohibited List as a prohibited substance in the S1. Anabolic Agents category.

As boldenone may also occur naturally at very low concentrations in the urine, WADA-accredited laboratories apply a specific analysis procedure called carbon isotope ratio mass spectrometry, or GC/C/IRMS, to differentiate between external administration and internal production. In 2018, there were 87 cases involving positive tests for boldenone, which represents 6 percent of all positives for anabolic agents globally in WADA-accredited laboratories.
