My goals are to be 300 and I'm at 260.
I get the desire to be tall is common but it's definitely not all it's cracked up to be ha. I love it yeah but it comes at the cost of never fitting into seats made for normal sized people (planes, etc) paying more for shoes because you're above standard size, common knee problems that tall people develop, having difficulty in the gym with form because your body is so much bigger than equipment is meant for, and the hindrance of being able to show muscle growth easily when all you want to be is a massive muscle beast.
I'm still working my ass off and won't stop. But if you wish you were taller don't. You have your own physical gifts as well, you just might not see them since we're our own worst critics.
