This is the issue. Kids that never thought about taking gear see someone like you pop up on their TikTok and think oh I can get big just like him if I take steroids. Which has always been the case, but with the mass proliferation of quasi gear promotion due to social media the influence is far greater than back in the day.
This is causing kids in much larger numbers than ever before to abuse gear, which has always been an issue, but now it's worse because of the prevalence.
I'm not saying you are the sole problem, but you are apart of it and directly contribute to influencing kids to negligently abuse steroids.
There are influencers who use PED's who push positive messages and strongly advise against gear usage, Noel Deyzel for example.
You can certainly change the tone and style of your content to strongly advise against abusing gear, especially if underage, while making content of your progress. Maybe add a disclaimer of sorts. If you really wanted to go all out you could even criticize Looksmaxxing while you're at it.
TLDR; Your content appears to glorify or promote gear usage and contributes to influencing kids to abuse steroids.
