Could I still grow?

Edit Post

I'm at 4.2 on the tanner puberty calculator. I'm 17 and go from just under 5'4 in morning to just over 5'3 at throughout the day. My mother is between 5'1-'2 however my father is right under 6 feet at about 5'11. My doctor said I should've at least reached 5'8. That makes sense as I have a 68.5in wingspan which is about 5'8.5. I have a nice chin strap and my cheek hair is starting to fill in. Basically the beard is taking shape however I still cannot grow a full beard. When I compare my upper body to a few classmates that have are also short around my height, I notice that I have a significantly wider/bulkier frame than them. I plan on lengthening femurs in early June 2015 as I'll be done with high school. Unfortunately I don't believe reaching 5'6-7 would be worth the all pain and costs of LL. And standing at a towering 5'4 I would have to lengthen 10 cm to reach 5'8. At least with that I can be 5'9 with shoes and with lifts I can stand confidently between 5'10-11. However I hope that I still have some growth left in my legs and that along with an expected torso growth spurt I hope I can reach at least 5'5-6. With that as my starting height I can lengthen the recommended 7.5cm and safely reach 5'8; 5'9 if I'm able to reach 5'6. Then I'd be 5'10 with shoes and for the f*ck of it if I decided to wear lifts (on occasion) I would stand at 5'11.

P.S. - You can call me Saul.

With HGH could I possibly max out any growth I have left in my legs if any? Also despite my relatively long wingspan in comparison to my height, my hands/fingers are small and childlike, would HGH make then noticeably bigger/longer? And finally would HGH increase my abdomen/chest size and increase my torso length? (Considering I'm still relatively young and am not finished with puberty)
