Testosterone dose decrease

I've been taking 0.4 ml(250 mg) every 2 weeks since october last year. Recently I got my bloodwork done(1 week after my dose) and my endo wants to lower my dose to 0.3 ml. My testosterone levels are 843.02 ng/dL. From what I know that's a healthy range to be in.

I'm feeling paranoid that she's one of those doctors that keep you on a low dose so you don't actually experience changes. I HAVE had some changes which I'm enjoying and I don't feel anything wrong mentally or physically.

Maybe there's someone here more knowledgeable than me, any ideas on how to proceed?
