From his eating “real food” campaign to endorsing glyphosate-based herbicides, Health Secretary RFK Jr. has had quite a variety of opinions. He is most notably known for being a prominent vaccine skeptic, taking actions over the past years to loosen the Centers for Disease Control and Prevention (CDC) recommendations and restructure the organization’s leadership. Yet recently, RFK Jr. has championed another perspective, one that is perhaps not as widely recognized as his other viewpoints and seems a bit counterintuitive: he supports the legalization of peptide injections.
Peptide injections have been gaining popularity in recent years because of the range of biological functions they can target. This has caused people, from celebrities, movie stars to even RFK Jr. himself to try the treatment. Essentially, peptides are chains of amino acids that are essential for tissue repair, protein synthesis, muscle repair and immune system regulation. Lauded by users for accelerating weight loss, anti-aging and injury repair, peptide injections are estimated to be a $140 billion industry by 2034. They are available for consumers to purchase through specialized clinics, compounding pharmacies, or, increasingly, on the gray market.
Broadly speaking, there are two “types” of peptides: those that are FDA-approved and those that are not. The most common FDA-approved peptide is GLP-1, which is used to treat Type 2 diabetes and obesity by decreasing blood sugar levels and suppressing appetite. GLP-1 appears in common brand names such as Ozempic and Wegovy, meaning that it is widely available for purchase. However, high pharmaceutical costs have caused consumers to shift towards the gray market to buy non-FDA-approved peptides. The “gray market” is a blanket term for the trade of goods via unofficial and unauthorized channels, which can include social media apps such as Discord or TikTok, often putting Americans into contact with retailers from foreign nations. Thus, by purchasing non-FDA-approved peptides, consumers put themselves at a significant safety risk. Non-FDA-approved peptides, such as the BPC-157 and CJC-1295, have not undergone extensive clinical trials to determine efficacy and health outcomes. Furthermore, scientists warn that these peptides have unintended side effects: BPC-157, for instance, can generate “free radicals” that damage DNA and proteins. There’s also no guarantee that the vials will contain the peptide the sellers claim they contain, as some have been shown to contain other substances like bacterial endotoxins, which are deadly to humans.
RFK Jr.’s plan to legalize the injections means that the 14-19 non-FDA-approved peptides, which were previously classified as posing health risks by the Biden administration in 2023, would allow licensed compounding pharmacies to produce and dispense new peptides with a prescription. RFK Jr. alleges that part of the reason legalization is necessary is to deter consumers from relying on the gray market, but experts claim that this move will do nothing to address the root cause of the issue. Indeed, as BioCentury writes, “Deregulation will not eliminate the gray market; more likely, it will create a second, more seemingly medically legitimized channel alongside it… The result would not be an evidence-based market, but a larger one, with the unregulated online tier continuing alongside it.”
This same sentiment is echoed by various FDA officials, who worry that a peptide legalization will shift healthcare standards away from a purely merit-based process that instead favors accessibility and rests on underlying financial motives. Given that America is a nation founded upon the principle of freedom, proponents of peptide injections and those of the wellness industry in general argue that the same logic should be applied to an individual’s right to make choices about healthcare. But scientists do not think that this notion of “choice” necessarily trumps the facts.
“What I’ve seen are the people who would profit the most from this saying that these drugs are safe,” said John W.M. Claud, a lawyer at Nelson Mullins in Washington, who previously worked for the U.S. Food and Drug Administration (FDA) and the Justice Department. “And what I haven’t seen is safety data that would tell me that these drugs should be more available.”
By legalizing peptide injections, the FDA may be setting a precedent that allows it to deregulate other drugs. This may further put the public at risk, against RFK Jr.’s stated aims of mitigating the influence of the gray market. For now, the compounding and wellness industries remain supportive of easing restrictions, while scientists and researchers contend that the evidence regarding peptides’ efficacy is shallow. While social media influencers may continue to boast youthful energy and rapidly healing injuries, RFK Jr.’s stance on legalizing peptides will likely create a rift between pharma, politics and science to be tested in the months ahead.
