Well I am 42, I had a vasectomy at 25. About 33 I fell off the cliff. I lost all energy gained a tone of weight. Well I move out of state took on a high stress job and in general felt like shit all the time. Last Dec I moved back and went to a new Dr, he ran a bunch of tests and found my T level at 203. He put me on injections once a week for 8 weeks then on 200mg/ml 20% cream daily. My numbers went up to 700 in 8 weeks. Well fast forward to this summer I broke my knee and left my cream in the hot garage for a week. I gave it no thought and went right back to using it, well the heat must of made it go bad. I started to notice a downward swing, I got retested in sept and it had dropped to 325. He got me back on injections ever 2 weeks with my cream. Next week he wants me to start with 200mg/ml 40% cream. I can tell it works and so can the wife. I fall a sleep faster, sleep all night, I want to get up in the morning and started having the morning wood again. I wish I would of done this 8 years ago. I am back to loosing weight and feeling all around much better!!!!!!!
