Can you buy some time of hormone supplement to make you taller?
Answer: Unfortunately, none exist. You could get risky and painful surgery... but that would lone gain an inch or two for months of solid pain whenever you move your legs.
You can't grow higher than your DNA say you're going to grow and forcing your body to grow earlier than it's ready for can be hazardous. Your bones need time to grow longer, your tissues need time to stretch and adjust to that growth, and anything faster than what they stipulation to take can cause tissue wreckage. Sometimes people have "growing pains" when they grow too quickly... that's basically from the tissue damage when their body grows faster than it's geared up for.
Yoga helps you to stretch your muscles and allow your joints to be more flexible, but it won't relief your bones grow longer. It's good to be doing, though, especially to keep your muscles moving and it'll facilitate to minimize any "growing pains" if you have a growth spurt.
Just give it time and you'll grow as elevated as your DNA says you should be (assuming no damage to the bones or injure to your health like smoking). Good luck!.
A series of HGH injections by a doctor at a cost of something similar to $10,000.00 or more can only help you if you are certainly deficient in HGH (and amazingly very few kids are) AND your growth plates are still open. The side effects can be rather horrendous.
Perhaps you might wish to investigate a web look into for hgh + dwarfism..
I doubt they sell it. You won't like the side-effects anyway.
