My wife encouraged me to talk to a doctor about possibly low testosterone levels because of increasing depression and irritability. When I was talking to him he started asking questions about difficulty of maintaining muscle/keeping fat off, energy levels, ED, and low libido. I had noticed all of those things but they came on so gradually that I did not realize how bad it had gotten till we started taking about it. I got tested and sure enough I was low. I started twice weekly at home subcutaneous injections about a year ago and man has it made a difference. My mood is much better, but because I’m just going back to normal levels I’m not aggressive. It is much easier to keep muscle mass and keep fat off. I have more energy, better sex drive, and better sex in general. I have not noticed any down sides so far. I like the at home thing because it is more smaller injections instead of fewer large injections so you maintain a more consistent level. I definitely do not think people should abuse steroids for “gains” but if you have low T and are seeing multiple symptoms from it I definitely think it is worth it to get back up to a reasonable level.
Mine is mostly lighting console show files of various concerts/comedians/dance performances I have been the lighting designer for. I know my use case is different than most people’s, but hey, you asked.
