question about height

This is my first post so I appologize if this has been asked a million times before

I am 15 years old, I weigh 160 pounds of muscle and also have a six pack (I am low in body fat high in muscle) I am 5 foot 10. My Dr's xrays estimate that I will be between  6' 3" and 6' 5", Is weight lifting safe for me at this age? I have hit puberty already, but all the men in my family have a late growth spert around 17 that makes us all very tall.

I just recently got into weightlifting around september, since then i went from a weak looking body at 140 pounds, to a much lower fat stronger body at 160, suppliment free. I just bought pro performance 100% whey protein from GNC and have been taking that now, is it safe to go with creatine and NO xplode that i keep hearing about?

Thanks

EDIT: I forgot to add my question, will lifting stunt my growth too much at this age?
