My SHBG is close to yours and I do well on smaller injections (20mg) EOD, it helps better control estrogen conversion to do the smaller testosterone and estrogen peaks when injecting smaller doses. Smaller injections every day (10-12mg) will help even further to reduce estrogen conversion, your Total T and Free T injecting everyday are pretty darn stable.
I however require an AI with my injections or trouble follows. The only thing I have to do to come out of a state of crashed estrogen in inject T without the AI, a couple hours later estrogen is high again.
