tnemo...... Its all about treating the symptoms, not the number. Numbers can be good markers to help gauge why you may or may not be feeling a certain way, but, as we all know, everyone is different. One guy may "feel" great at 650, while another guy might be in the bowels of hell at 650. It all depends on the individual. Thats why we make it such a strong point, at maximus Hormone Replacement Therapy (HRT), to really get a good feel for how our clients are "feeling" and what their personal/mental/emotional/family goals are, so that we can address therapy accordingly.
