If your growth plates haven't closed yet and you haven't finished puberty, you can take aromatase inhibitors and human growth hormone simultaneously and it can make you grow significantly taller. Don't recommend doing drugs but ngl the risk profile is pretty decent.
Aromatase inhibitors, when used for up to three years in combination with growth hormone, may effectively and safely help very short adolescent boys grow taller, new research suggests.

It's a relatively safe medical procedure that is normally used for kids that have severely stunted growth but hey, why not try it on someone who is average height... might be 6'4 by the time you're 20. Obviously a doctor won't prescribe you anything cos you're normal but these drugs are SUPER easy to get
you didn't hear this from me though
