I just got finnished with prostrate cancer treatment,i was given shots to shut down my test production to shrink my prostrate for radiation treatment. I was without any test for 6 months and i can tell its much worse than 400 or 500 test levels. Big strenght loss,vertually no pumps and all my joints hurt. Now that my test is coming back theres a big difference in the way i feel. I felt fine with my normal test levels,i didnt have any of the low test symptoms,but i do feel better when im on a cycle. Im old now,have a lot of nagging injuries especially shoulders which prevent me from training the way i use to so my goal is to stay lean and muscular......
