I'm quite open about my usage in real life because I want to be honest about how I achieved my weight loss - I'll also show some pride in all of the lifestyle changes I made, but I don't hesitate to mention the GLP-1 use and impact it has had. I'm not ashamed of it and if me being open helps normalize it, all the better.
But most people on the internet that I speak to that are on them have had specifically negative encounters from people learning - lots of moralizing, lots of denigration. A whole lot of them now specifically don't bring it up unless explicitly asked.
Indeed, aside from online, where I don't feel consequences from admitting it, very few people know I've taken a GLP1. None of their business, and I don't need to waste seconds of my finite lifespan nurturing their need to feel morally superior. Let everyone worry about their own problems, I'll worry about mine. And I wish they were all as easily solved with GLP1s...
