Help my dad out here

I've been trying to get him on TRT for awhile. My dad just turned 70 yo and is in great health. He recently had bloodwork done and went back today for the results and to go over it with the doctor. I told him to call me but he didn't until he was leaving and told me what his doctor put him on. She is starting him on " 75mgs " Test E, 1 shot a month... She wants him to take one shot a month of 75mgs for 4 months and then go back and go over how he feels. I had him go back in and he's currently waiting for her to come back out so I can speak to her on the phone about this protocol. I see this issue over and over, so many doctors are not qualified to be prescribing TRT. They know nothing about it and either give you absurd amounts weekly (200mg+) or in my dads case barely any and have you doing 1 shot a month. I'll be talking to her shortly and will update how the phone conversation goes. I wanted to make this thread for my dad so he can read everyone's thoughts on this and hear it not just from me but the whole community here on why 75mgs once a month is a terrible choice. Thank you
