Selective androgen receptor modulators (SARMs) are a new class of substances that have similar properties to anabolic steroid agents, but with marked reduced androgenic properties. As SARMs have the potential to be misused for performance enhancement in sport due to their anabolic properties as well as ability to stimulate androgen receptors in the muscle and the bone, they have been prohibited at-all-times by the World Anti-Doping Agency (WADA) since 2008 under section S1.2 of the List. Ligandrol is one of the more popular SARMs. A WADA accredited laboratory identified in the urine of a female athlete bishydroxy-ligandrol, the major ligandrol metabolite at approx. 90 pg/mL (specimen A) and 200 pg/mL (specimen B). The athlete challenged this anti-doping rule violation and requested a hair test to document possible incidental exposure. About 7 weeks after urine collection, a hair specimen (brown in color and > 20 cm in length) was collected and segmented in 6 x 1 cm segments. Ligandrol was tested by liquid chromatography-tandem mass spectrometry after alkaline incubation and extraction. With a limit of quantitation at 1 pg/mg, no ligandrol was identified. It appears that the athlete was unaware her husband was taking the substance, which was confirmed by his hair test (ligandrol at 7 and 8 pg/mg in 2 x 2.5 cm segments). The Court of Arbitration for Sports accepted the athlete's explanation that she had been exposed to ligandrol through the exchange of bodily fluids with her husband and lifted her provisional ban. This case demonstrates that drug transfer between two subjects is possible during intimate moments.
选择性雄激素受体调节剂(SARMs)是一类新型物质,其性质与合成代谢类固醇药物相似,但雄激素性质显著降低。由于SARMs具有合成代谢特性以及刺激肌肉和骨骼中雄激素受体的能力,有可能被滥用于提高运动成绩,自2008年以来,世界反兴奋剂机构(WADA)一直根据《禁用清单》S1.2条对其予以全面禁止。Ligandrol是较受欢迎的一种SARMs。一家WADA认可的实验室在一名女运动员的尿液中检测出双羟基-Ligandrol,这是Ligandrol的主要代谢物,浓度约为90 pg/mL(样本A)和200 pg/mL(样本B)。该运动员对这一反兴奋剂违规行为提出质疑,并要求进行毛发检测以证明可能的意外接触。在尿液采集约7周后,采集了一份毛发样本(棕色,长度>20 cm),并将其分成6段,每段1 cm。经过碱性孵育和萃取后,采用液相色谱-串联质谱法对Ligandrol进行检测。定量限为1 pg/mg,未检测到Ligandrol。看来该运动员并不知道她的丈夫正在服用这种物质,她丈夫的毛发检测证实了这一点(在2段2.5 cm长的毛发中,Ligandrol含量分别为7和8 pg/mg)。体育仲裁法庭接受了该运动员的解释,即她通过与丈夫体液交换而接触到Ligandrol,并解除了对她的临时禁赛。这个案例表明,在亲密时刻,药物在两个个体之间转移是有可能的。
