MOST SPORTING bodies prohibit(禁止) performance-enhancing drugs. The Enhanced Games revels in(陶醉于；尽情享受) the possibilities they offer. The competition, which kicks off(开始（活动）) on May 24th, allows athletes to use all sorts of substances, provided they are licensed and that they are administered under a doctor’s supervision(在医生监督下使用).
大多数体育机构禁止使用兴奋剂。增强运动会（Enhanced Games）则乐于接受它们带来的可能性。这项于5月24日开幕的比赛允许运动员使用各种物质，只要这些物质获得许可并在医生监督下使用。
Many athletes competing in the games have been cagey(谨慎的；讳莫如深的) about their plans. But in April Mitchell Hooper, a Canadian who has twice won the World’s Strongest Man competition, revealed his in detail. Aside from Adderall, a stimulant, Mr Hooper’s “stack(（药物的）组合)” consists of various anabolic-androgenic steroids (AAS), a class of compounds that are chemical cousins of testosterone(睾酮的化学近亲), the chief(主要的；首要的) male sex hormone.
许多参赛运动员对自己的计划讳莫如深。但今年4月，两次获得世界最强壮男人大赛冠军的加拿大人米切尔·胡珀详细公布了自己的方案。除了兴奋剂阿德拉（Adderall），胡珀的“组合”还包括多种合成代谢雄激素类固醇（AAS），这类化合物是主要男性性激素睾酮的化学近亲。
That makes sense: AAS are some of the most potent(强效的；有力的) performance-enhancing drugs known, especially for boosting strength and power. They will probably be doing most of the heavy lifting(繁重的工作（比喻）) for every athlete at the games. And they are popular with non-athletes, too: one meta-analysis(荟萃分析；元分析) from 2014 estimated that 6% of men have used them at least once(至少一次). But just how effective are they?
这说得通：AAS是已知最强的性能增强药物之一，尤其在提升力量和爆发力方面。它们很可能在运动会上为每位运动员承担大部分“重任”。AAS在非运动员中也很受欢迎：2014年的一项荟萃分析估计，6%的男性至少使用过一次。但它们到底有多有效呢？
