Those Viral Bodega Peptides Aren’t Actually Peptides
8 min read
Summary
The Mr. Green bodega sits on a busy stretch of Bedford Avenue in Brooklyn, New York. Near the counter, you can buy the usual assortment of candy, gum, rolling papers, and soda. You can also purchase tiny vials of injectable peptides. So we did. And then we sent them to a lab.
Mr. Green is one of several shops that went viral this summer for selling peptides, a broad class of amino acids touted for their ability to aid in everything from weight loss to injury recovery.

While the FDA has taken recent steps to loosen regulations, and many large telehealth platforms like Hims and Mochi are preparing to start selling a broad array of peptides, many people who take these substances today are purchasing them through questionable channels.
“The FDA needs to shut down these black markets,” Fred Mills, a longtime pharmacist and an executive at the nonprofit Americans for Safe and Effective Medicines, tells WIRED. Mills, who is based in Louisiana, says he’s had discussions recently about the dangers of people purchasing peptide products at convenience stores and that he warns those who do so to consult with a physician first.
If a peptide vial actually contains little more than water or saline solution, the worst that might happen is that someone loses money on a useless product. But some mislabeled peptides can contain ingredients that cause harm; a woman died this year after receiving a peptide injection from an unlicensed medical spa in the Bronx.
“My concern with the peptide industry is, we’re legitimizing products, and we have no idea what’s in them. We have no idea about the safety, accuracy profile, or whether they’re adulterated or misbranded,” says Darshan Kulkarni, an attorney focused on pharmaceutical regulatory compliance. In the traditional pharmaceutical sales world, steps are taken to ensure prescription accuracy and product safety, from visual inspections to barcoding.
“Someone selling a product at a bodega doesn’t know how to do that,” Kulkarni says.
“The FDA has warned companies selling products labeled ‘for research purposes’ or ‘not for human consumption’ when those products are marketed directly to consumers for human use,” an agency spokesperson who declined to give their name tells WIRED in an email. “Additionally, the FDA has warned telehealth companies for marketing drugs directly to consumers and for making false or misleading claims regarding compounded GLP-1 products offered on their websites. The FDA will continue to take action, where appropriate, to protect public health.”
The agency did not answer WIRED’s questions about whether it has contacted or taken enforcement action against brick-and-mortar sellers of peptides labeled research-only, like those sold by Mr. Green.
There have been some enforcement actions. Earlier this summer, a man in South Bend, Indiana, was sentenced to six years in prison for selling “research use” peptides that were illegally imported from China—a major source of peptide ingredients—and were adulterated with steroids. Still, the enforcement atmosphere is loose enough that it remains easy to buy unapproved peptides both online and at brick-and-mortar medspas and other locations.
Kulkarni believes that the relatively low number of enforcement actions taken against the research peptide industry is related to the Trump administration’s attitude that “regulation stifles innovation, and therefore they believe that it is in the interest of patients to allow them to decide what products to take.”
As for Mr. Green, it did not respond to a written list of questions provided by WIRED. When we visited in early September, the menu in the window was gone. But a smaller version was next to the counter, and the peptides were still for sale.
