The Russian who loaned Donald Trump’ssocial media platform Truth Social $8 million previously set up websites selling dodgy sex pills, according to records seen by The Daily Beast.

The flagship product sold by these sites, Vimax—which promises longer sex and a firmer erection—has prompted warnings from health regulators in the U.S. for containing hidden ingredients that may endanger health. The Food and Drug Administration warned consumers not to buy the supposedly natural male enhancement supplements, and told anyone who had bought the tablets to throw them out.

The sites where the pills were sold included vimaxtrialoffer.com which was registered in the name of Anton Postolnikov, 40, according to public domain ownership records. The Gmail account used to set that up was also used for vimax-detox-trial.com and vimax-trials.com. For communications regarding the pills, a series of email addresses @vimaxgroup.com were also set up and registered in Postolnikov’s name.

The Russian entrepreneur, who reportedly has family links to the Kremlin, has a history of success in niche online businesses such as providing financial services to porn stars and camgirls.
