In my office, the in-house gym instructor asked me to have protein, amino and steroids. Almost twice a week he insists that I use those. From my experience, I don't want to use those things at all, because I didn't do any heavy lifting or any heavy weight exercises. I feel good after the workout and this helps me concentrate on my work. But he keeps asking me to use all of the supplements and he also shows me photos of all of the types of products on a regular basis. I don't want to say NO to those products because I want to maintain a friendly environment, and he might get offended if I do so. Is there any way around to refuse him politely? As of now, there is no such policy in the office. Is there some kind of official policy that I could ask HR to implement? My present work culture is a bit different from the western office culture. We usually spend days or even a complete week in the office. This is the reason that I use the gym frequently, and that's why I want to maintain a friendly atmosphere.
As an update, the country of origin doesn't matter because I am unaware of the national laws. And I am not planning to sue anyone. I'll be here for a short period of time. Thus I am not interested in country specific solution.
