My Doctor gave me the option to go on HGH. I am only going to be able to take 2 - 3 units a day five days a week. I have options between Humatrope, Norditropin, Genotropin, Omnitrope, Saizen and Trev-Tropin. I would like to know if one has any benefits over the other, or are they all the same thing made by different companies. It is going to be added to my test cypionate dose of 80 mg a week.
