There are not many, there are some and they’re outliers that danced between raindrops based on the genetic lottery. It might seem like “many” based on what you see on social media, but it really isn’t.
The worst that can happen is that you spend, literally, the rest of your life on medication to play catch-up correcting problems that started from using anabolics too young.

Talking to your doctor about your plans is probably the best idea right now.
