I've Had Gynecomastia For 2 Years Now. I'm 17 And

I've had gynecomastia for 2 years now. I'm 17 and 195 pounds 6'3". I have a stocky build and a lower body fat percentage. I was wondering if you could tell me about any supplements that could remove it or reduce it at least? I've been taking zinc but it hasn't really worked at all or at least it's not noticeable. I'd appreciate some help! Thanks!
