This is not at all true, you are only hearing about the negitive experiences, men who respond well to TRT aren't on forums seeking help, mostly those who are having problems are what you are seeing.
Take me for example, when I finely got on the appropriate protocol, by then I had multiple mineral and vitamin deficiencies and is when I started having problems. It took my two and a half years to figure it out.
You are lost if working with an ordinary doctor who doesn't really prescribe TRT often, none of my endocrinologist have any clue how to monitor/manage men on TRT. You basically need a GP, endocrinologist, cardiologist all wrapped up into one.
I wouldn't have ever joined any of these forum if I hadn't run into problems.
