Man, if what you're doing is working for you, stick with it while you can. Stunting growth should certainly be paid attention to as a possibility if you start a dht-inhibitor. But really, do yourself a favor and before you start anything like that research the best you can into the effects of DHT, and DHT inhibition, and the brain. Ignore all the idiots that tell you people are fatuous fear-mongerers for saying such a thing and just do it. Before you do something like that at such a young age, be sure you have as much a grasp as you can on the complexity of inhibiting hormones and just what that entails.
