16, 5’9, squeaky voice, no beard, am I cooked?

[Motivoice]

I don’t think I’ve grown since last summer and I don’t have a beard yet. I’m LTN and I don’t wanna use peptides. I work out and do cardio a lot. I’m 154 pounds and I’m healthy. Will I ever exceed 5’9? I’m taller than both of my parents. My brother who’s a few years older than me is 6 foot. Is there any hope for me or do I just rope?
