There is a testosterone ratio that they apply for IOC governed sports I think they allow up to 3 to 1 of the amount of the normal male or female. But the various drug cheats are boosting their ratio to 3 to 1 and taking HGH(which isn't allowed), they are taking steroids that shed fat and only put on lean muscle. Until recently peptides which seemed to fuel the Yam drug party weren't detectable and that affects the nervous system. The minute peptide tests became available the male Yams became mortal again like they were pre-08.
This site had a dormant poster who sometimes posts on some lame stream sites and he was spot on with the drug scene in track and field. I don't know if he is gym rat or a former athlete but he knew what was up when it came to the latest PED regiments.
PS ETH is obviously on what beats the tests she ran a 10.5X which is the unofficial world record in the 100m and nobody but people that believe in Santa Claus think Flo Jo was clean in 88' and her official world record wasn't wind assisted and dirty too. Also her mandible is rather prominent now when he she first burst on to the scene she has a normal looking jaw. SAFP now looks like a mini bodybuilder and is running 10.7X times in her mid 30's? Shericka Jackson just ran a 21.8X and looks like a tanks too. Nothing to see here lets move on.
