Well I just turned 70 and have been taking TRT, for over 10 years. Started off with using a gel but it had a slight smell to it so quickly switched over to intra muscular (thigh) injection 1ml of 200mg testosterone cypionate every 2 weeks. I get checked by my urologist at least 2x a year, complete blood work and prostate exam. I’m not saying you should do it but for me I believe it works. I’m 6’2”, 220 lbs and work out at least 3x a week. Not a bodybuilder or weightlifter but can do 8-10 reps at 225lbs on the bench, but I have always lifted weights.
Still need by little blue pill for insurance. I think it helped me, maybe more so mentally but I do feel better all around. But there “can be” potential side effects.
Especially if you have prostate issues, diabetes or some other underlying problems.
You really need to have an honest talk with your Dr and weigh all the possible side effects. The only issue you really notice is your “nuts” shrink since your body stops making testosterone. No big swinging ball sack.
Good luck.
