While this bust isn't that surprising, looking at do Nascimento's world athletics page, specifically the progression tab, is quite interesting.
In 2016 he would have been comparable age to a college freshman, between 2016-2020 he's running at about the level of a good D2 athlete in a number of events 1500-10,000m including steeplechase but really nothing of note. Then 2021 he drops a 2:06.11 in Valencia.
Is the general consensus that he was clean until 2020ish? Are low-level anabolic enough to take a good D2 runner/ D1 non-national meet qualifier D1 athlete and get them to a 2:06 level within one year? Or are we thinking there's definitely epo microdosing as well?
Wild to think that drugs can take someone who has been competing in national level athletics since he was 15 (2013) from a 3:48/14:17/29:32 level to 2:06 in one year.
