Your DAN doctor will work with you to find the correct dose... my son weighs 35lbs but needs 4units [0.04ml] every day... for his best results... could be due to his low body fat or whatever... just know there are lots of different dosings... I have also heard that Dr. Neubrander may also be doing daily injections for some of his patients.. the key to these treatments is in the indivudual patient parameters.
