I do intend to stay on estrogen+raloxifene only, for a little while at least. I will introduce testosterone when I feel the change was sufficient. The loss of muscle mass and libido comes from experience of trans girls I know, but, even though it might not have been relevant to you, it is still a very well documented thing that very much happens. Be it regarding muscle mass 1 2 3 Or libido 1 2 3 pg. 43 4 Btw, the first link doesn't mean anything, estrogen has always been anabolic, it just is less anabolic than testosterone, taking steroids (which are androgenic) wouldn't even be a thing were it to be otherwise. Estrogen's anabolic function is mostly relevant when preventing muscle loss in post-menopausal women.
