You won't find much real world research as it's locked up and not on pubmed. Most AAS was developed and researched in the 50's and 60's by government scientist on both sides of the Cold War. The AAS arms race was played out on the Olympic battlefields. Sometimes someone on here will pop an East German or Russian study, I'm not sure where they find them. And I can't read Russian lol That one dude Anthony Roberts use to find stuff all the time. He was a journalist or something.
