Well in your case it may be a good thing, you don’t want to be on the other end of the spectrum. You can always through more testosterone at high SHBG.
Look at it like this, when my Total T is 500, Free T is 21 top of the ranges, a guy with a high SHBG that binds strongly would probably need a Total T of 1000-1200 to equal the same Free T as myself. Higher SHBG is general healthier than lower SHBG.
Insurance doctors will not allow levels >800, if you go there they will force you to stop TRT for a month, not fun. You need levels higher than >800 to increase Free T high enough.
