What is your body weight? Usually dosing of HGH is based upon a patient's body weight for that type of protocol. According to prescribing information regarding HGH the calculation would be as follows.
body weight/2.204622 = bw in kg
Min dosage bw in kg x 0.018
Max dosage bw in kg x 0.375
Usually you would want to start just slightly up from the min. Now if it turns you are sensitive to the HGH some people will back down 0.5 IU from that dosage.
Hope this helps.
