Not in a million years would I ever equate steroid use to a relapse. I used to use an illegal substance that resembles rock salt HEAVILY, and I would say building your body is one of the best forms of sobriety out there. I went to rehab, AA, NA and all that other shit, and from what I gathered a relapse is you going back to what you used to do. Just because you begin using another substance doesn't mean you're relapsed. Just like when you go to AA meetings and there's 300 people outside smoking, they're not relapsed, but they kept a habit in place of another one.
Ingesting said substance is not worth throwing away all the time I've spent busting my ass in the gym and in the kitchen.
I don't know if I can say that stuff on these forums
EDIT: took out drug name and act of doing drug
