I started treating low DHT along with my Cyp injections and like you have low SHBG. I eventually transitioned all the way to cream and never looked back. Cream to the scrotum sends my DHT off the charts. Look at if you need to use the cream more than once per day. I did a complicated time...
The simplest advice out there is when it comes to carbs, if they come in a bag or a box, are to be avoided. Then increase protein intake as much as possible to the 1G/Lb of body weight standard.
You should be able to get a great start on that alone.

Oral is going to impact the liver so pick your poison if going that delivery route because of HCT.
