Tips for someone finally starting T

After about 6 years of trying to get on T my appointment is in a week and I am very happy to be starting.

Now I've done so much research it's not even funny but there's always new things to learn.

I know about the balding and the atrophy and all of the scary things that may happen and am ready for it but what are some things you all wish you knew before starting?

And for bottom growth specifically how long did it take you to see changes? I know for some people it takes longer than others.
