I'm 41 and I've been on TRT for almost a year and it's been a struggle with the Dr. It's hard when you know more than the Doc but you can't say to much or they get suspicious about it. Mine started me on Test Cyp at 50mg's a week, not enough to do squat and has now raised it to 100mg's a week. I feel great at 200 a week so I just supplemented my script on my own and took the numbers down before blood work. My Doc is very limited on his knowledge and doesn't even run E2 numbers when doing blood work, he says it's not relevant. I pay to have my own bloods done periodically. Some guys I know that are on TRT tried the gel and had horrible results. They couldn't get a consistent Test number and it was a pain to put on daily and keep away from kids and wife. It's also a lot more expensive than injectable if you're paying for it yourself. TRT changed me for the better when I found a good number to run at. Just my .02.
