Is it ok for a 14 year old to use 10kg dumbells?

I'm 14 and I've been lifting for quite some time. I've looked into this a lot and I can guarantee you won't be screwed for life your doing yourself a favour I've been training for two years and I feel really confident and glad because of it. If you also go the extra mile and eat well like I did you can look really lean but since then I put on a bit extra weight for more muscle
