As part of our commitment to transparency, I like to keep everyone informed about important developments within the industry. Recently, a number of rumors have been circulating that have created unnecessary concern. Please take a moment to read this entire message for clarity and accurate context. Industry Update Over the past year, several large companies—some owned by high-profile influencers—have entered the market. These companies have been openly selling RUO (Research Use Only) products while simultaneously promoting or implying human use, and in some cases marketing to practitioners under separate entities. Many of these companies sponsor major biohacking, anti-aging, and peptide conferences and actively solicit business from doctors and clinics. At the most recent A4M conference, rumors began circulating—originating from some of these same companies—suggesting they were discontinuing GLP products and claiming that government agencies would soon begin shutting down RUO companies altogether. To date, these claims remain unsubstantiated. Notably, many of these rumors trace back to one of the largest peptide influencers, who continues to openly discuss human use. This is a practice we are firmly opposed to at Step One and do not promote in any capacity. To be clear: these are rumors only. That said, we are seeing ripple effects overseas. One of our manufacturing partners has temporarily paused its peptide division, citing increased scrutiny driven by unlicensed operations and irresponsible promotion on social media. They expressed concern that poorly manufactured, untested, or counterfeit products—often tied to unknown labs—have drawn unwanted attention to the industry as a whole, including legitimate manufacturers.
