And he's probably on one pill a day of an antiviral drug combo which makes his HIV undetectable which means he needs the HGH and test and win and AIs not at all. But his doctor is also gay, probably also on the same antiviral pill, and appreciates the effects of the PEDs himself (which another gay doctor at the same practice prescribes to him), so he's cool and writes those scripts for your friend too. And your friend uses a box a month and sells 3? Not too shitty since his $20 copay gets him 4 boxes every 4 weeks.
OR your friend could have developed AIDS and actually need AAS and 18iu serostim daily to prevent wasting and extend his life, in which case I'm sorry for speculating about the more usual situation for aging gays.
