While the details behind this are highly suspect at this time, it is worth mentioning that Richard Rodriguez, who was the victim of a DEA raid in February of last year, has gone on record to name several high-profile personalities that served as some of his clients.
Rodriguez was the co-owner of a gym called Iron Addicts and was accused of buying steroids from China and then manufacturing and distributing them in the United States.
The three clients named in the video (which you can watch above) are actors Mark Wahlberg and Josh Duhamel as well as current RAW superstar Roman Reigns.
These are of course just allegations that are completely unsubstantiated at this point in time so they should be taken with a grain of salt. Reigns had previously gotten a wellness policy violation but it was for Adderall rather than steroids. Another odd detail is that Richard was supposedly introduced to Reigns through an informant. What makes that strange is that Reigns was never questioned during the investigation.
