there are some posters on allthingsmale.com who are highly educated about TRT but have horrible results -because they're in their 50's or older, obese, don't exercise and have terrible diets.
the real long term damage from TRT is caused by the mechanical act of injecting imo
Hope you are being sarcastic. I am not sure how much damage a 22 gauge needle does, but it probably isn't much. It's rare if I bleed even one drop of blood when injecting, the needle slips through the skin like a knife through butter. I never have pain at the injection site nor have I ever had an infection.
Obviously, TRT does not replace a healthy diet and reasonable exercise. It is possible for someone to be on TRT and be unhealthy, but it unlikely that TRT is the cause of this. I currently weigh what I did in my early 20's, so no obesity here. Can't help getting old, it only natural. So far my health has been good to great. If I keep going the way I have been, I could see 100....Lord have mercy!
