Unfortunately, that doesn't work for me. I've been researching SHBG for years. When I saw the Swedish and German epidemiologic studies which linked testosterone to daylight and SHBG levels, I thought that perhaps D3 was the answer. I've started supplementing with 4,000, then 8,000, and now 10,000 IU D3 for many years (at least 3) and there is no impact that I can see on SHBG levels for me. I think that there are probably different mechanisms for different people that cause high SHBG. For some, D3 seems to work well, for others Boron seems to work well, for me, nothing had any appreciable affect until I tried Winstrol (Stanozolol). I have to become a felon to get it, but such is the American medical and legal system.
