It's fucking rude, annoying, inappropriate and distracting. Not to mention pathetic in my opinion. Go do the research if you want a good cycle or wait until it's private and you aren't interrupting their workout. Don't assume someone even wants to talk to you about it even if it is obvious they're on a cycle. No one has asked me at the gym but they do stare. The only people are ones I know in another way and it's never at the gym. And usually they juice too and are just wanting conversation. Fuck tards that do that piss me the fuck off
