Probably more numbers than you want or need, but shows you how SHBG changes. During my first 16 months of TRT, I tested my blood every month.
Pre TRT: 104+
After 30 days: 97.2
After 60 days on TRT and 30 days on Danazol: 60.4
After 90 days on TRT and 30 days OFF of Danazol: 101.1
After 120 days on TRT and 30 days BACK ON Danazol: 33.2 (about April 2018)
Oct 2018: 27.3
Dec 2018: 40.55 (unknown reason for increase)
April 2019: 24
Sept 2019: 12 (!)
Jan: 2020: 32 (cut Danazol dose in half from Sept 2019)
