Just a thought. We know from several medical publications that thyroid hormone treatment will increase SHBG. My personal experience and labs corroborate this too. Have you considered adding in desiccated thyroid tables (like Armour Thyroid) to your protocol. if you do, my suggestion is to start at 15mg per day and SLOWLY raise the dose by 15 mg every 2-4 weeks, giving your body time to adjust to the higher doses. I would then redo SHBG labs after 4 weeks at 60mg per day and see how you are doing.
