The reality is that you'll reach 6'1" if it's in your genetic destiny. You can easily go to the doctors and see how close your growth plates are to closing, if they aren't closed already and they'll let you know...
It's a pretty easy process.
However at the end of the day there are no supplements/products you can take to increase your growth if you're already receiving the nutritional standards for health through your diet. Some say mk677 helps with growth but it's hardly proven in teens and there isn't enough evidence on it. So if you want to waste a couple grand and supplement with it throughout your teens then maybe it's worth it for you, however your genetics will be the ultimate determiner in your final height given that you meet the nutritional standards for being a half decent, healthy human being.
