Do they make pills that make adults taller
I am not really getting any results for any pills but there are surgeries you can have done to make you taller. You should be able to take hormones as well.
Your height is determined by your genes. There is nothing you can take, or do, to make yourself taller, other than be healthy so your body has the ability to grow to it's pre-determined height.
You can't take pills to make yourself taller. Height is determined by your genes, and there's nothing you can physically do like taking a pill to make yourself taller.
