越来越多的十几岁男孩在网上追求夸张的身材改造——练出大块肌肉、甩掉脂肪，并将全过程记录下来供数百万人观看。
但在一些 viral 的身材背后，潜藏着一个令人不安的趋势：使用一种从未被批准用于人类的强效药物。
快速蜕变——与一个冒险的选择
16岁的扎伊德·莱拉（Zaid Laila）表示，他不想花数年时间锻炼，才能拥有自己在网上看到的那种身材。
“为什么要等10年……我明明可以在不到一年内就做到，”他说。
这位来自达拉斯郊区的高中生开始在社交媒体上记录自己的健身历程，他的蜕变很快吸引了关注。他的视频展示了更匀称、更健硕的身材——这类身材往往在各大社交媒体平台上备受称赞。
但莱拉毫不避讳自己是如何达成这一效果的：“靠大量类固醇和大量锻炼。”
他告诉哥伦比亚广播公司新闻，他使用合成代谢类固醇已有约10个月，其中包括群勃龙，一种专为牲畜研发、从未获批用于人类的强效药物。
一种本就不该给人用的药物
群勃龙，常被称为“群宝”，旨在促进牛的肌肉生长。它在美国被列为第三类受控物质，未经处方持有或分发均属违法。
加州大学旧金山分校专攻青少年健康的儿科医生杰森·长田（Jason Nagata）表示，合成代谢类固醇会损害心脏、肝脏和肾脏——而群勃龙可能更加危险。
“群勃龙药效极强，副作用也更严重，”长田医生说。“这种动物用药物没有任何安全的（人类）适用指征。”
类固醇使用：从体育赛场到社交媒体
几十年来，类固醇使用大多与竞技体育挂钩，但如今使用动机已经发生转变。
“现在很多人根本不参加任何体育运动，他们使用这些药物只是为了看起来更好，”长田医生说。
非营利组织“抵制数字仇恨”2023年的一项研究发现，2020年至2023年间，美国带有特定标签的推广类类固醇药物的TikTok视频累计观看量至少达5.87亿次，其中72%的观看者年龄在18至24岁之间。
刷一刷社交媒体，这种趋势随处可见：蜕变视频、健身网红和前后对比照片似乎都在展示立竿见影的效果。
“随着社交媒体的普及，男孩们面临着前所未有的练出肌肉的压力，”长田医生说。
莱拉表示，这类图片直接影响了他的决定。
“看到别人这么做，你就会想自己也试试，”他补充说，这些药物也很容易买到。
“一点都不难，”他说。“只要想找，任何人都能弄到。”
由悲剧敲响的警钟
在弟弟因使用类固醇去世二十多年后，小唐·胡顿（Don Hooton Jr.）表示，这个问题只会愈演愈烈。他的弟弟泰勒（Taylor）在高中时开始使用合成代谢类固醇，当时有人鼓励他为了体育锻炼变得更强壮。停药后，他患上了严重的抑郁症，并于2003年自杀身亡。
胡顿现在领导着泰勒·胡顿基金会，该基金会旨在向年轻人宣传性能增强药物的危害。
“我们如今看到孩子们在问群勃龙是否安全，”胡顿说。“这是一个大问题。”
他表示，社交媒体从根本上改变了年轻人接触这类物质的方式。“毒贩已经从阴暗的小巷……走进了我们家中安全的四壁之内，”他说。
“每个人都在拍自己的视频。他们想成为下一个社交媒体明星，为此不惜一切代价改变身材，哪怕使用非法药物，”胡顿说。
尽管存在风险，一些青少年仍只关注短期回报。
“如果我30岁时心脏病发作，那就发作吧，”莱拉说。
家长们应该留意哪些迹象
这些警告信号并不总是显而易见的。长田医生告诉哥伦比亚广播公司新闻，家长们应该留意孩子是否有过度锻炼、避开与家人朋友共进晚餐，或是其他影响社交的变化。
在某些情况下，家长甚至可能在无意中强化了这种行为：他们称赞孩子的身材变化，却不知道这些变化是如何达成的。
莱拉的家人正在和他沟通此事。他的父亲海瑟姆·莱拉（Haitham Laila）告诉哥伦比亚广播公司新闻，他非常担心儿子的健康，也对儿子用来为使用类固醇辩解的错误信息感到无奈。
扎伊德·莱拉表示，他了解这些风险——但仍会坚持自己的选择。
“我还是会（使用类固醇），”他说。“我知道可能会有什么后果。”

How social media is driving teens toward steroids and extreme body transformations
April 6, 2026 / 12:39 PM EDT / CBS News
A growing number of teenage boys are chasing dramatic body transformations online — building massive muscles, shedding fat and documenting it all for millions to see.
But behind some of the viral physiques lies a troubling trend: the use of a powerful drug never approved for humans.
A rapid transformation — and a risky choice
At 16 years old, Zaid Laila says he didn’t want to spend years working out to build a body like those he saw online.
“Why wait 10 years … when I could do it in less than a year,” he said.
The high school student from suburban Dallas began documenting his journey on social media, where his transformation quickly drew attention. His videos show a leaner, more muscular physique — the kind often celebrated across social media platforms.
But Laila is open about how he got there: “A lot of steroids and a lot of working out.”
He told CBS News he’s been using anabolic steroids for about 10 months, including trenbolone, a powerful drug developed for livestock and never approved for human use.
A drug not meant for people
Trenbolone, often referred to as “tren,” is designed to increase muscle growth in cattle. It is classified as a Schedule III controlled substance in the United States, making it illegal to possess or distribute without a prescription.
Dr. Jason Nagata, a pediatrician specializing in adolescent health at the University of California, San Francisco, says anabolic steroids can damage the heart, liver and kidneys — and trenbolone may be even more dangerous.
“Trenbolone, because it’s so powerful, it has even more significant side effects,” Nagata said. “There is no safe [human] indication for this animal drug.”
Steroid use, from sports to social media
For decades, steroid use was largely associated with competitive sports, but the motivation has shifted.
“There are many people now who aren’t actually participating in any type of sports who are using these drugs only for the purpose of looking better,” Nagata said.
A 2023 study by the nonprofit Countering Digital Hate found TikTok videos under certain hashtags promoting steroid-like drugs have been seen at least 587 million times in the U.S. between 2020 and 2023, with 72% of those views from users between the ages of 18 and 24 years old.
Scroll through social media and the trend is hard to miss: transformation videos, gym influencers and before-and-after photos appear to showcase rapid results.
“With more social media, there have been really extreme pressures for boys to build muscle,” said Nagata.
Laila says those images played a direct role in his decision.
“Seeing people do it is what makes you want to do it,” he said, adding that the drugs are also easy to obtain.
“It’s not hard at all,” he said. “Anyone can get their hands on it if they try.”
A warning shaped by tragedy
More than two decades after losing his younger brother to steroid use, Don Hooton Jr. says the problem has only grown. His brother, Taylor, began using anabolic steroids in high school after being encouraged to get bigger and stronger for sports. After stopping the drugs, he experienced severe depression and died by suicide in 2003.
Hooton now leads the Taylor Hooton Foundation, which educates young people about the dangers of performance-enhancing drugs.
“We’re seeing kids today asking if trenbolone is safe,” Hooton said. “That’s a major problem.”
He says social media has fundamentally changed how young people are exposed to these substances. “[The] drug dealer has gone from a dark alley … to the safe four walls of our home,” he said.
“Everybody is filming themselves. They wanna be the next social media star, and they’re doing whatever it takes to change that physique, even if it’s using illegal drugs,” said Hooton.
Despite the risks, some teens remain focused on the short-term rewards.
“If I have a heart attack at 30, I have a heart attack,” Laila said.
What parents should watch for
The warning signs aren’t always obvious. Nagata told CBS News parents should look out for obsessive workout routines, teens avoiding meals with family and friends, or other changes that impact socializing.
In some cases, parents may even unintentionally reinforce the behavior by praising physical changes without understanding how they were achieved.
For Laila’s family, conversations are underway. His father, Haitham Laila, told CBS News he is deeply concerned about his son’s health and overwhelmed by the misinformation his son has cited to justify steroid use.
Zaid Laila says he understands the risks — but continues to make his own choices.
“I’m still going to do [steroids] ” he said. “I know what can come with it.”
