‘You turn yourself into a lab rat’: The influencers selling experimental drugs as ‘miracle’ injections
“Why would I want to wait six months when I can inject peptides and look like the best version of myself in 30 days?”
Walker Harrell speaks from behind a screen showing off his lean, muscular body that most people can only achieve with a strict diet and exercise regimen. But he tells his listeners that the way to achieve this is not through hard work.
Instead, he says he injects peptides and by following the link in his bio, you too can look “younger”, slimmer and tanned.
Social media platforms, including TikTok and Instagram, are full of creators claiming they can help speed healing, clear acne, and build thicker muscles with a simple injection.
Even popular podcaster Joe Rogan, who does not sell peptides, claimed on his popular podcast that he utilized the benefits of the experimental peptide BPC-157 to heal an injury. The Joe Rogan ExperienceHe said the tendinitis in his elbow resolved “within two weeks.”
Messages can be particularly effective for young men. Videos he saw Independent He suggests that the compounds are essential for “look maximization,” a trend in which people try to increase their physical attractiveness, and even suggests that taking them during adolescence can affect your “results” as you transition into adulthood.
But beneath the ripped bodies and perfect skin there is a dark world full of unknowns and risks.
Peptides were first discovered with the isolation of insulin in the 1920s and are now a life-saving treatment for millions of people with diabetes. But many others, including those promoted on social media platforms, are still considered “experimental” and have never been subjected to rigorous clinical studies. In the UK and US these are sold under the warning label: “For research purposes only. Not for human consumption”.
To talk IndependentThe risks of purchasing such research chemicals are “significant”, experts said.
Professor of anatomy at Lancaster University, Dr. If peptides sound too good to be true, they probably are, says Adam Taylor, and those who use them “run the risk of turning themselves into a lab rat.”
Dr Taylor explains that peptides are short chains of amino acids that act as the building blocks of proteins. They work by acting as messengers that tell certain parts of the body what to do; whether this is repair, growth or healing.
“What we have at the moment is a lot of peptides coming onto the market that are advertised as helping you recover faster,” says Dr Taylor. “Many of these are quests for the holy grail of renewal and rejuvenation.”
He adds that new compounds are often marketed and advertised through influencers who have “limited scientific authority” to talk about their legitimacy, which means audiences don’t get to see the full picture behind the image being sold.
GHK-CU, a copper-based peptide, claims to have “exceptional anti-aging, regenerative and even anti-cancer properties,” according to one online retailer.
Another set, known as the ‘Wolverine stack’ due to the Marvel character’s remarkable healing properties, promises to speed recovery and support muscle recovery.
However, Dr Taylor says if this is proven we will see it used in medical settings.
“If these peptides were safe for human use, we would use them to treat patients,” he said. “Some of them haven’t been tried in patients. But in some cases where they have been tried, they don’t show the benefits we need to make them effective enough to bring them to market through the NHS.”
Instead, Dr. These unedited peptides carry some risks, Taylor says: “If you’re allergic and you stick a peptide in a muscle or even a vein in your bloodstream, you could end up with a really serious anaphylactic and potentially life-ending reaction to something unknown there,” he said.
“As an untrained professional, sticking a needle into your body carries high risk. If you hit a nerve or blood vessel or introduce an air bubble into your vascular system, you will be causing potentially serious, if not lifelong, damage.”
He adds that there is even some suggestion that they may activate pathways that cancers use to attack the body; However, he emphasizes that this is not proven by direct evidence.
“Users run the risk of turning themselves into a lab rat,” he says. “One of the biggest challenges with a lot of these peptides is that you don’t know your own physiology. You don’t understand what the underlying things are and what they might trigger.”
The sudden explosion of compounds on social media appears to be aimed at young men; Dr. Taylor says this is “particularly risky.”
“Not only is your body evolving in ways that you can see, but you’re also continuing to evolve physiologically,” she explains. “The hormones you produce for various tissues in the body still don’t have their full potency. You don’t want to disrupt those hormonal pathways.”
Because peptides are not regulated in the UK, it is difficult to obtain precise data on how many people use them. However, analysis of Google search trends shows that there are almost ten times more searches for the compound in 2025 than in 2020, and research shows that more gym-goers are using this compound. performance enhancing drugs to have more than three times Since 2014.
Dr Taylor told Independent It may take many years for the full story behind the peptides to emerge. “I think it will be like that when this generation reaches middle age,” he says. “It may have some desired effects, but it may also have undesirable effects, and I think that’s what we’ll see with a lot of these products in the future.”
Her warnings come from Dr. Dr., medical director of the It’s Me & You aesthetic clinic. It was echoed by Laura Grainge. he said Independent It has seen a significant increase in patients experiencing complications, mostly injection site reactions, after purchasing research chemicals online.
Dr Grainge added that the risks “come entirely from the lack of regulation”, as customers have no guarantees about the purity, sterility or actual content of the products they buy.
“Because these are not proven medicinal compounds, they can cause unpredictable and potentially serious systemic problems such as hormonal imbalances, heart palpitations, anxiety, and unexplained inflammatory responses,” he added.
“The risk is not worth the unproven, short-term gain.”
The Medicines and Healthcare products Regulatory Agency (MHRA), the UK’s medicines regulator, said: Independent That it would “ignore” claims that the products were for “research purposes” if it was clear that the claims were used to evade drug regulations.
A spokesperson added that it is “strongly advised against the purchase and use of unauthorized medical products, particularly those promoted on social media.”
Meta said it removed accounts brought to its attention. IndependentIt added that content “intended to sell or promote the consumption of potentially unsafe drugs, products or supplements” is not allowed.
A TikTok spokesperson said its community guidelines “prohibit trading, marketing, or providing access to regulated, prohibited, or high-risk products and services,” adding that this “also includes regulated substances, such as products marketed for weight loss or muscle gain.”
“We banned the #peptide hashtag and removed shared accounts for violating our Community Guidelines,” the statement said.
Joe Rogan and Walker Harrell have been approached for comment.
