hello all, I am newly 19 and started trt 3 days ago. I have a couple of questions. where is the easiest and safest way to inject? will doing this make anything bigger/smaller? say if my level was at 300ng/ml and I took 100 would that put my levels up at 400ng/ml? is taking it once every 2 weeks really effective or should it become more frequent to maintain better levels? And one last question-I'm on testosterone replacement therapy once every two weeks. my Dr wants me to come back 6 weeks after the first injection but don't take it two weeks prior to my testosterone test. I'm still l really new to this and I was wondering what he is trying to accomplish. any ideas?(asked yahoo answers and no luck). anything you can educate me about this would help immensely, thanks!
