Steroids: they’re infamous for their use in sports. But they’re also found in inhalers, creams to treat poison ivy and eczema, and shots to ease inflammation. The steroids in these medicines aren’t the same as those used to build muscle. In fact, they’re all based on yet another steroid— one our body produces naturally, and we can’t live without.

类固醇：它们因在体育运动中的使用而臭名昭著。但它们也存在于吸入器、治疗毒藤和湿疹的药膏，以及缓解炎症的针剂中。这些药物中的类固醇与用于锻炼肌肉的类固醇不一样。事实上，它们都是基于另一种类固醇--一种我们身体自然产生的类固醇，而且我们不能没有。
