I disagree, it depends on the strength of the cream. My father is on a compounded 200mg cream with T levels above 1000+ and it only takes a small quarter sized amount/day.
I mean obviously your not going to want to use cream to reach double that number like you would with 400mg/injectable. But, for a base to run epidrol or other PH on top of, sounds like it could work.
I know years ago my wife was prescribed a test cream to help her with her libido. I don't remember feeling any effects from it after getting it on me during the deed.
