Okay, I'll admit it could be an age thing. I've genuinely never heard of it. Out of this long 15 page list of people serving drug sanctions (I had to control F lol) only 2 people were from nandrolone. So it's not super prevalent In Track and Field today, but I supposed it could've been before I was old enough to know what PEDs were. When Karissa S. was brought in, it just irritated me, and I had to point out that in the real world (not just Let's Run) I can almost guarantee the vast, vast majority of 22-32 old athletes don't know what this is. And again, if you're not doping, why would you be looking up all these different drugs all the time? No one does that. I mostly look up the ones that are tested positive for most prevalently, and the ones most like to be consumed unintentionally. In the past few years, nandrolone has not been one of those.
Also, it wasn't really a question. You flat out said the coach lied, said he should be banned (probably not seriously but still) and compared it to super super well known drugs like EPO and HGH. You also insinuated Nike is orchestrating some sort of mass cover up with its messaging. (b.)
If you merely said "Hey, this was a pretty big anabolic back in the day. I think it's weird these older coaches haven't ever heard of it. Haven't you guys all heard of it?" Then that's cool; fair question. Honestly, you probably meant it that way actually.. we kind of communicate things oddly on this site for some reason lol.
