My dr is a prof bodybuilder worldwide and I have been on HGH 2 iu daily and I was doing my first month of injections wrong so I am glad I brought in my bottle and he showed me how to inject, near my navel I alterate left and right side and the other area is upper thigh and he held the needle side ways sliding under skinas if you were sewing something and you still can see the needle through skin, inject in HGH and it bubbles at where the tip of needle is inserted, draw out needle. and then it goes in your system....now I have results!!!
