yep, it depends. i know i felt like i had to rush into it, but the time went by surprisingly fast and i'm glad it went at the pace it did. after starting therapy to the time i got my first shot was about 5.5 months.
i went back and forth on the T thing for a bit, mostly to do with my belief system. that's what the therapy is there for, to work things out and make sure you're ready etc.
