I'm 42 have been working out 5 days a week for 3 years. Currently I’m on a very long Test E only cycle 1000mg a week. I was just about to end it when I heard from a few people that a cycle of 800mg's a week for as long as a year is safe and beneficial. These people who mentioned this are in the medical field, experienced body builders and just regular Joes who seem to know their stuff. Is this true?
