Caveat - We have said this before, and it’s worth repeating, young people often have valuable insight into how technology is being used and experienced today. The key is whether we, as adults, are willing to take the time to listen. This article was sparked by a thoughtful conversation with a teen who shared what he and his friends are currently seeing in their social media feeds. Even he recognized some of these trends as concerning, which made the discussion all the more important. This article also builds on our recent piece, “Looksmaxxing: The Growing Pressure on Teen Boys to Optimize Their Appearance,” as this emerging trend clearly fits within that same broader online movement (1).
If you have a teen on social media right now, there is a growing chance they are being exposed to something called “peptides.” Promoted heavily by influencers in fitness, wellness, and “self-optimization” online spaces like TikTok, these substances are often framed as a shortcut to better health, faster recovery, improved appearance, and even enhanced confidence (2)(3).
Peptides are not inherently dangerous, in fact, they are a normal part of human biology. They are short chains of amino acids that help regulate important processes in the body. Some medically approved drugs, like insulin or certain weight loss medications, are peptide based, and have gone through rigorous testing and regulatory approval. However, what is being promoted online is something very different. Many of the peptides trending on social media are not approved for human use, not regulated for safety or quality, and often sold as “research chemicals” online
Even though influencers may present them as cutting edge health tools, these products have not been validated through proper human clinical trials and are often marketed far beyond what the science supports.
One of the most important concepts parents and caregivers should understand is something researchers call science exploitation. This is when real science is used to give credibility to unproven claims. Because some peptide based medications (like those used for diabetes or weight loss) are effective, it creates a misleading leap in logic that all peptides must be beneficial. However, that assumption is not supported by evidence.
It’s important to note that the science behind many of these trending peptides is still in its early stages. Much of the research is limited to laboratory or animal studies, which often do not translate into safe or effective use in humans. Many of these substances never make it through the full clinical trial process, and some have been discontinued altogether due to concerns about safety or a lack of meaningful results.
What is often missing from online conversations is any mention of these limitations. Instead, social media is filled with something far more compelling to a general audience, personal stories and testimonials from influencers. While these accounts can sound convincing, they do not replace the kind of rigorous scientific evidence needed to determine whether a product is truly safe or effective.
Scroll through social media and you will hear statements from “influencers” like:
“This changed everything for me”
“I don’t even look like the same person anymore”
“This is what actually works”
These types of messages can carry significant weight, especially for teens who are already trying to make sense of body image, performance expectations, and their own identity. When confident, well-known figures share personal stories of dramatic transformation, those narratives can feel far more relatable and convincing than clinical explanations or scientific data.
This influence is amplified when it comes from recognizable public figures such as "Clav" (4), Other influencers such as Joe Rogan has spoken openly about peptides such as BPC-157 and TB-500, often referred to as the “Wolverine stack,” suggesting they helped with injury recovery. Actress, Gwyneth Paltrow, has discussed peptide injections as part of her personal wellness and beauty routine, helping bring these substances into more mainstream lifestyle conversations, particularly among teen girls and women (5).
When teens see these messages repeated by people they recognize or admire, it can reinforce the perception that these practices are both effective and acceptable. Over time, this kind of exposure can shape beliefs about health, risk, and what it means to “optimize” the body, often without a full understanding of the science or potential consequences behind those choices.
It is important to recognize that personal stories are not the same as scientific evidence. While they may sound convincing, they are based on individual experience, not controlled research or verified outcomes. As highlighted in a CBC article, much of the current excitement around peptides is being driven by influencer narratives rather than solid scientific proof (6).
For young people, repeated exposure to these types of messages can begin to blur the line between marketing and medicine. Over time, what is essentially promotion can start to feel like trusted health advice, making it more difficult to separate fact from persuasion. One of the most concerning aspects of this trend is that many of these substances are injected which introduces immediate and longer term risks, such as :
Infection from improper injection
Contaminated or mislabeled products
Unknown dosing or ingredients
Lack of medical supervision
Public warnings from Health Canada (7) have gone even further, noting that unauthorized peptide products can lead to:
Hormonal disruption
Organ damage
Blood clots
Mood changes
Potential cancer related risks
There is also a broader issue that often gets overlooked and that is we simply do not know the long term effects of these peptides that are sold online, outside the medical supervision of a doctor. Even if a product is exactly what it claims to be, there is little to no data on how repeated use may impact the body over time. This is an important teaching moment for families because accessibility online does not equal legitimacy.
A common narrative in social media is that peptides are “natural,” and therefore safe, but this is misleading. Yes, peptides exist naturally in the body, but injecting synthetic or unregulated versions can be dangerous. These substances can interact with multiple pathways in ways that are not fully understood, potentially leading to unintended consequences. Natural does not automatically mean safe, especially when taken outside of a controlled medical context.
What we are seeing with the promotion of peptides in social media is not just about one specific trend, it’s part of a much larger shift in how health information is being shared and understood in today’s digital world. Medical language, terms that were once largely confined to doctor’s offices and clinical settings, is now being used widely across social media platforms. At the same time, influencers with no formal medical training are increasingly positioning themselves as trusted voices on health, wellness, and performance. Complex decisions about the body and long term health are often presented as simple, quick solutions that promise fast results with little discussion of risk or uncertainty. This creates an environment where the lines between medical advice, personal opinion, and marketing begin to blur.
There is also a subtle but important normalization of peptides taking place. Practices that would have once raised immediate concern, such as self injecting substances outside of a medical setting, are now being framed in some online spaces as routine, even responsible, parts of a wellness lifestyle. When young people see this repeatedly, it can begin to reshape their understanding of what is safe, acceptable, or typical behaviour. For teens, this shift in what feels “normal” is significant, and can influence how they interpret risk, how they evaluate information, and ultimately, the choices they may consider making.
The rise of the peptide trend in social media offers a clear example of how quickly health related misinformation can take hold when it is presented in a way that feels authentic, relatable, and appealing, which is especially true for older teens. When messages are wrapped in personal stories, confident delivery, and promises of transformation, they can carry more influence than the actual evidence behind them.
For parents and caregivers, the goal is not to try to block every trend or control every piece of content a youth or teen may encounter. A more effective and sustainable approach is to help youth build the skills needed to question, assess, and think critically about what they are seeing and hearing online.
In today’s onlife world, information is everywhere. The real challenge isn’t access, it is discernment. Helping youth and teens learn how to separate credible information from persuasive messaging is one of the most important forms of protection we can offer, especially now given AI!
