My endo started me on a low dose and has recently increased it. It seems to be common practice to start you off low. According to my endo, sometimes the levels aren't accurate to the person's well-being. He's met transmen starting out their transition whos blood levels indicated one thing, but the way they felt indicated another. For me, I'm sure theres something going on inside me for the last month, but i can't really tell, and after having told my endo that I dont feel any different, he upped my dosage. I'm pretty big too, I'm 6'1" and weighed (at the time) 215 lbs (currently down to 203). I think size has little to do with dosage since its relevant to genetics and not hormone levels. Example: My dad's side of the family has high T-levels, but my facial features are soft and not too male looking, they've always been this way. Even though my T-levels might very well be higher than the average MAAB person. Hence why sometimes levels are not cohesive with the way you feel or look.
