Online Hype Around Injectable Peptides
Influencers are promoting injectable peptides as a sort of “glow up potion,” claiming they can help with everything from hormonal acne to hair thickening, back pain relief, and even chronic UTIs.
These peptides are primarily designed for research use and are not approved for human consumption, yet they are increasingly available through unregulated online platforms.
Experts have raised alarms about the potential dangers of these variable substances. Recently, U.S. Secretary of Health Robert F. Kennedy Jr. mentioned plans to approve around 14 injectable peptide drugs for public sale, amplifying the claims of their benefits.
Firstly, what are peptides?
Peptides are essentially short chains of amino acids that occur naturally but can also be manufactured. They either serve as components our body utilizes, like collagen peptides, or function as signaling molecules similar to hormones that instruct our body to perform vital tasks, as explained by Dr. Michael Bonning from the Australian Medical Association.
The glucagon-like peptide 1 (GLP-1) is a well-known example, pivotal in regulating metabolism and a major reason weight loss medications like Ozempic and Wegovy work differently than other drugs, according to Bonning, who chairs public health for the association.
GLP-1 is a natural hormone, found alongside other peptides like insulin and growth hormone, that can profoundly affect body functions. Because of this, Bonning emphasizes the need for caution when considering their use.
Most therapeutic peptides require a prescription, and some are prohibited, making it unsafe for consumers to purchase these online, according to Bonning.
Does injecting peptides actually work?
The supposed benefits of these peptides are largely exaggerated and not backed by scientific evidence, Bonning notes. Many haven’t undergone clinical trials, which raises a red flag. “Even if data exists, you can’t trust that what you’re receiving is what it claims to be, or that it meets safety standards,” he adds.
What are the risks of peptides?
Bonning warns that these research chemicals are not safe for human use and could pose serious risks, given their uncertainty in toxicity. For example, injectable tanning peptides have been linked to skin cancer risks and reported kidney issues and brain swelling.
Dr. Ian Musgrave from the University of Adelaide, who purchases peptides for research, highlights that while they are suitable for lab use, their purity may not meet the standards required for medical treatment. “Even if the peptide is the right length and sequence, it might not fold correctly when injected, potentially causing immune responses,” he explains.
Concerns grow even more with new peptides like retatrutide, which, despite promising clinical data, still lack sufficient trials to dictate proper usage or understand side effects. Musgrave insists taking such substances without a prescription means individuals are at risk of serious complications.
What do experts recommend?
Bonning concludes there’s no safe dosage for these unregulated peptides because their content is unknown. He criticizes those promoting these products, highlighting the irony of recommending unapproved peptides while discouraging trust in everyday foods. He advises caution, noting that while topical peptide-infused products can be beneficial, injectables pose significantly different risks that don’t warrant self-medication.
