Loss of height is due to the way the women's hormone cocktail handles the calcium. My family has a history of height shrinkage as they age, more so in my female relatives. My youngest sister informed me that she has osteoporosis, she's 50! My case so far that my muscle mass and strength has actually increased in the 4 1/2 months on the HRT with no loss of bone. Muscles, especially your heart are known to leech calcium from the bones in times of hunger and stress, I have neither of these problems. I never had this muscle mass increase happen in my 58 years! HRT effects each of the M to F transitioners differently. I am still 6' 2", but my younger brother shrunk an inch and he's on T for his different prostate problem.
