it's a bit more complicated than it seems.
the steroid injected (probably into the epidural space) was a cortisone derivative, not an anabolic steroid. It was injected for it's anti-inflammatory properties to help with sciatica (nerve root irritation from a prolapsed lumbar disc).
Corticosteroids are locally and systemically catabolic and immunosuppressant. They predispose to specific types of infection, in particular fungi and tuberculosis. In many cases, fungal infections come from a patient's own gut, thru their bloodstream and seeding from the blood into various target tissues like the brain, bone, liver and spleen.
In this case, contamination of the injected solution with fungus was very unlikely-- it was most likely a rare complication of the medication being delivered.
The point about being concerned about UG lab quality assurance is a good one tho. That's why boards like this one provide such an important service to the BB/PL community (those who use AAS)-- they act like a Better Business Bureau for the UG labs: those who stand by their product and use basic QA/QI principles are rewarded, while fly by night operations are financially punished when their reputation gets trashed.
