肽为什么突然火了？一场从减肥药开始的健康热潮

这一两年，从健身房到社交网络，好像人人都在讨论它。

For the past year or two, from the gym to social media, it seems everyone is discussing them.

先花一分钟，把肽这个概念说清楚。

Let's take a minute to explain what a peptide actually is.

说白了，肽就是一小段氨基酸连起来组成的东西，本身就存在于我们的身体里。

Plainly put, a peptide is a short string of amino acids linked together, something that already exists in our bodies.

它一点也不神秘。

It's not mysterious at all.

比如大名鼎鼎的胰岛素，其实就是一种肽。

For instance, the famous insulin is, in fact, a kind of peptide.

那问题来了，一个身体里本来就有的东西，怎么突然就火了呢？

So here's the question: how did something the body already has suddenly get so hot?

这背后，其实有一个很关键的推手，就是减肥药。

Behind this, there's a key driver: weight-loss drugs.

这几年，像司美格鲁肽这类减肥药特别火，效果也确实明显，而它们，恰恰都是肽。

In recent years, drugs like semaglutide became hugely popular and clearly effective — and they happen to all be peptides.

于是很多人就顺着想：既然这些肽能减肥，那别的肽，是不是也有各种神奇的好处？

So many people reasoned: if these peptides help you lose weight, don't other peptides work too?

但其实，"减肥药是肽，所以别的肽也一定管用"，这个逻辑本身，就站不住脚。

But actually, "the weight-loss drug is a peptide, so other peptides must work" — that logic simply doesn't hold up.

再加上，网上一大批网红和博主，天天都在安利各种肽。

On top of that, a huge crowd of influencers and bloggers online promote all kinds of peptides daily.

他们号称，打了肽，能长肌肉、能加快受伤后的恢复、能抗衰老，甚至能改善脑子。

They claim that with a peptide shot, you can build muscle, recover from injury faster, fight aging, even sharpen your mind.

其中被吹得最神的，是一种叫 BPC-157 的肽。

The one hyped as most miraculous is a peptide called BPC-157.

在他们嘴里，肽几乎成了包治百病的神药。

In their telling, peptides have practically become a cure-all miracle drug.

所以这两年，越来越多的普通人，也开始给自己注射各种肽。

So over the past two years, more and more ordinary people have started injecting all sorts of peptides.

可是，医生和专家们，却一直在泼冷水。

But doctors and experts keep throwing cold water on it.

他们的担心，主要集中在两点。

Their worries center on two points.

第一，是有没有用的问题。

First: the question of whether they even work.

很多被吹上天的肽，比如 BPC-157，到目前为止，一个正经的人体临床试验都没有做过。

Many of the peptides hyped to the skies, like BPC-157, so far haven't had a single proper human clinical trial.

绝大多数所谓的证据，都来自在小动物身上做的实验。

The vast majority of the so-called evidence comes from experiments on small animals.

换句话说，很多人是把自己的身体，当成了试验场。

In other words, many people are turning their own bodies into a testing ground.

第二点，也是更严重的一点，是安全。

The second point, and the more serious one, is safety.

监管部门抽查过网上卖的肽，结果发现，差不多有四成，要么剂量不对，要么含有没在标签上写明的成分。

When regulators spot-checked peptides sold online, they found that nearly 40% either had the wrong dose or contained ingredients not stated on the label.

更让人后背发凉的是，有研究提示，某些肽可能会加速体内异常细胞的生长，理论上，甚至可能和癌症扯上关系。

Even more chilling, research suggests some peptides may speed the growth of abnormal cells in the body — in theory, possibly linked to cancer.

除此之外，这类东西还可能带来水肿、头疼、血压变化等一系列副作用。

On top of that, these substances may cause a string of side effects like edema, headaches, and blood-pressure swings.

这里还有一个值得注意的现象。

There's another telling phenomenon here.

这些肽，很多都是从中国等地，通过网络卖到世界各地的。

Many of these peptides are sold from places like China, over the internet, to buyers around the world.

为了绕开监管，它们大多打着"仅供科研使用"的旗号，实际上却卖给了普通消费者。

To skirt regulation, they mostly fly the banner of "for research use only," while actually being sold to ordinary consumers.

这个市场到底有多大？

Just how big is this market?

有数据显示，光是二零二五年的前九个月，美国进口的这类东西，就达到了三亿多美元，比前一年直接翻了一倍。

Data shows that in the first nine months of 2025 alone, U.S. imports of such substances hit over 300 million dollars — double the year before.

而今年年初，美国的一位高官，还公开表示，要放开对一部分肽的限制，这更是给本就火热的市场，浇了一把油。

And early this year, a senior U.S. official publicly said he'd loosen restrictions on some peptides — which only poured more fuel on an already blazing market.

说到底，肽不是什么点石成金的仙丹。

Ultimately, peptides are no magic elixir that turns stone into gold.

在正规医疗里，它确实有它的用处；可一旦变成网上乱买乱打的东西，风险就被无限放大了。

In proper medicine they do have their uses; but the moment they become something bought and injected carelessly online, the risks are amplified without limit.

真正的健康，从来没有那么便宜的捷径。

Real health has never had such a cheap shortcut.

好，今天这个话题，就先聊到这里，我们下次再见。

Okay, that's where we'll leave this topic today; see you next time.
