Ah. Just saw 5%. SorryYes, T3 is one of the very few things that will increase SHBG. With it, I lowered my RT3, raised my SHBG from 16 to 24, and I have been injecting now just 3 times a week instead of every day. I apply a 5% cream every morning before I leave for work too. Thyroid, thyroid, thyroid. It makes as big of a difference in your life as TRT.
