My Experiences
I'm 54 and soon to be 55 and have been doing cycles for many years.
Actually something like 30 years would be more accurate. For the last several I have been doing regular cycles with the standard time off theory between them.
Although it has been suggested to me to go on TRT my personal reasons for not doing so are more monitary than anything else. By the time you have the doctors visits, blood work etc it can get very costly. Then some docs want to do all their little experiements with jel's, patches, low doses to start and then finally (maybe) get to the point where you can actually get your own 10ml vials and self administer a person would have gone through many months, experiemnts and many 1000's of dollars.
For me it's just been a lot less hassle to gather all my goodies from sources I trust, plan out my next cycle and self administer.
I am stronger than a lot of guys in the gym, my stamina is unbelievable, re-coop time is non existant and my girlfriend is totally worn out. LOL
