It was a little bit of trick question because you are focusing on high doses so I apologize but 42 mg/wk is all I take. Few years ago I started at 80 mg/wk and free T just kept going up after my body adjusted and SHBG dropped. I have had SHGB as low as 11 but right now it is around 17. I am probably an outlier (am I really?) but many won't know if lower doses work for them because of the more is better mentality. I believe nobody should be tied to the mg/wk is what I HAVE to take or I CANNOT go down past this mg/wk. We are all so different so if something isn't working decide and just try it. It's how you feel AND levels. My sleep, cognitive function, libido, and everthing else is better. At 80 mg/wk I was exhausted all of the time and put on about 10 pounds of water weight and after titrating down (not a pleasant experience) I lost all of that and I can work out longer. You may be surprised that 60 mg/wk may make you feel much better. The first 3 weeks will not be a pleasant experience even though after a few days or week your sleep may improve. You cannot let hormones in flux dictate that your change is a failure. You have to give it 3 months at any change to know.
