For what it’s worth…
You’re 16, and at this stage I think you should just focus on training hard and eating well, and things will fall into place on its own. I’m not saying you can’t or shouldn’t, but I don’t think you need to really get your mind wrapped up in certain protocols, supplements, etc. that are probably considered minutiae. I’d say enjoy your time right now, take advantage of the things you can get away with, and just keep training hard. It’s something I’ve learned, get the basics and the big picture right, and only worry about those small details when one actually needs to.
Just my $0.02.
