DIY peptide injections, which promise to boost everything from weight loss and muscle-building to longevity and sexual health, are a high-risk wellness fad that keeps on growing. Health experts have raised major concerns about these products’ safety because they are not regulated by the U.S. Food and Drug Administration or any other health authority.

Risks of DIY Peptide Injections

These products could have bacterial, fungal, chemical, or heavy metal contamination; their purity could be lower than indicated; and the dose promised may not be what you receive. In July 2026, the CEO of one peptide company was sentenced to 70 months in prison for selling tainted and substandard products.

A recent study published in the journal Public Health Reports found that people who purchase peptides from the online gray market are likely to make lots of mistakes when injecting them, which can result in serious harm. The study recruited 10 college students and 10 adults in their 60s to demonstrate how to correctly dissolve a semaglutide GLP-1 peptide product, draw it up into a syringe, and inject it into a mannequin’s arm or belly.

The results showed that on average, people did fewer than half the steps correctly. Some participants chose vials with liquid to dissolve the semaglutide powder that were expired, had floating particles in them, or were cloudy. Many people struggled to determine how much liquid to add to dissolve the powder and the correct dose to draw up once it was dissolved.

Need for Regulation and Education

The study highlights the need for regulation and education on the safe use of peptide injections. The FDA has not said whether it plans to adopt recommendations to add six widely used peptides to a list of substances that can be formulated and sold by compounding pharmacies. However, even if it does, the recommendations apply to only a small handful of such products that consumers can purchase, and they don’t address the fact that these products are not tested for safety or efficacy.
