1. Metformin 500mg in the morning 2. No refined sugars in my diet 3. tamoxifen 5mg 3X per week (also for other reasons) 4. Low fat Paleo diet 5. Berberine (recently ordered this, will take 500mg 2X daily) 6. Coffee 3 cups of coffee per day The goal is to raise my SHBG from 14-15 range to 20-30 range. The hope is that by doing this I can tolerate testosterone injections much better.
