I am currently on TRT and have noticed major improvements in my mood and sex drive. I was worried at first but after the results of the injections, I am glad my doctor recommended it and walked me through all of the benefits vs. possible side effects. I am doing self-injections once a week and my levels have normalized. I do regular blood work every 3-6 months just to ensure the dosage doesn't need to be adjusted. I didn't have any major side effects, except I did notice a bit of acne but very minor and subsides with proper skin care. If your T-levels are low I would recommend it, if it is an option provided by your doctor. Honestly I wish I didn't need it but I am glad it was an option for me due to my low levels.
