While intended strictly for laboratory research, a growing number of these products were being marketed and sold to consumers for personal use, often with misleading claims. The FDA has identified this as a significant regulatory challenge, as it allows companies to bypass the stringent approval processes required for human therapeutics.
Warning letters and public statements from the FDA in October 2025 signaled a tightening of oversight on RUO labeling. The agency is cracking down on the improper marketing of these peptides, which are often sold online through various e-commerce platforms and social media channels. The trend of unapproved peptides, including those falsely labeled as RUO, spreading through biohacking communities and online marketplaces underscores the FDA's imperative to address these "gray market" drugs to protect public health.
Beyond specific peptide products, the FDA's October 2025 enforcement activities also encompassed broader issues related to drug advertising and promotion.
