Icarus was filmed in 2017 highlighting how easy it is for these guys.
Oh yeah, I love the beginning of the documentary. The second half however, if I remember correctly, goes full political, borderline propagandist, but knowing how sharp you are, you probably saw it coming too.
Nonetheless, the first half of the documentary, where the "expert" shows how to get away with pretty much everything, was really well done and truly enjoyable.
I also would like to add, that creatine isn't a banned substance, and something completely natural, so not steroid (you can find some in meat).
I was using it, because I don't take a rest day, meaning I do exercise everyday, and it really helped with the extra rep, and of course I gained mass.
As for the hair loss though, it's difficult to find studies about it, it supposed to be linked to DHT production, I think in all honesty it must mess with your hormones, so probably a tad terrible for you, and not as "harmless" as all companies are claiming.
I don't know enough about this stuff even though I should as the family business makes some of these things as they are Everlast. They are busy with an energy drink currently which is launching in the next few weeks and expect it to do well because of the name.
