Creatine is still very much a thing, but I think everyone actually knows what it is and what it does and it's not treated as a magic bullet any more.
Mainly what seems to have changed is that steroids and TRT have exploded in popularity, and a scary number of under 18s are doing it.
Apart from that I couldn't tell you, it's all happening on Insta and TikTok now and I don't participate.
