I have no idea if that random post about Rand Paul business ventures is accurate or made up. I can't find any other info or verification on it. Until proven, it is standard internet rumor or propaganda.
Grok said this, although Grok is not the best source:
"There’s no evidence he currently earns income from medicine. Some sources speculate about business ventures, such as stakes in medical equipment companies, but no concrete documentation supports this as a current income source."

Rand Paul's Financial Connections
There is no specific information in the provided context about Rand Paul making money directly from medical supply companies. However, the context does mention that Rand Paul was involved in founding the National Board of Ophthalmology (NBO), which was an alternative certification system for ophthalmologists. This board was not accepted as an accrediting entity by organizations such as the American Board of Medical Specialties, and its certification was considered invalid by many hospitals and insurance companies. The NBO was dissolved in 2011.14
Additionally, in 2021, Rand Paul disclosed that his wife Kelley Paul had purchased a stake in Gilead Sciences, a company that manufactures an antiviral drug used to treat COVID-19, on February 26, 2020.5 This investment was made well before the public understood the full threat of the coronavirus, raising questions about potential insider trading, but there is no indication that this was related to medical supply companies or that Rand Paul made money from it directly."
