You missed the bottom paragraph:
Meldonium was added to the World Anti-Doping Agency (WADA) list of banned substances effective 1 January 2016 because of evidence of its use by athletes with the intention of enhancing performance. . . . An alarmingly high prevalence of meldonium use by athletes in sport was demonstrated by the laboratory findings at the Baku 2015 European Games.
WADA classes the drug as a metabolic modulator, just as it does insulin. Metabolic modulators are classified as S4 substances according to the WADA banned substances list. These substances have the ability to modify how some hormones accelerate or slow down different enzymatic reactions in the body. In this way, these modulators can block the body's conversion of testosterone into oestrogen, which is necessary for females. Based on the overall effects these drugs have, they have been banned since 2001 from men's competitions and 2005 for women's.
