The dosage you state is correct but is not based on your actual weight
. It is the general guideline based on lean body mass/ideal
body weight (IBW) which is a better indicator of replacement needs. IBW is based on sex, height, and frame size.
Not everyone needs full replacement and as Barb135 stated, we are all different and it is better to work upward slowly based on lab results than to risk overdose based solely on a general guideline that may or may not be right for you.
