You are in puberty and have a distinct height from your brothers, there's many reasons as to why you're not as tall as you should be, assuming it's predisposed for you genetically and your brothers didn't just get really lucky.
Now as for if you should use hgh, absolutely, as soon as possible even, your window isn't closing anytime soon (assuming you're on a steady course of adolescent development) so if you start using hgh now you're going to ascend a great ton, possibly even more than your brothers depending on how long you would hypothetically use it.
