I have run a number of contest cycles without prop, or with less prop. You will find that you will need more AI to control estrogen and dry out, but it can be done. The more test you use, the more AI you will need. I have found that when using long acting test, some guys can run it right into the show with enough AI, while others are better off reducing the dose several wks out. I find that when I have used a long acting test into the show, I like to cut the dose down at about 4 wks out and use more masteron because I want to keep hormones high. Everyone is different though, if you are looking good and running your full dose of test at 4 wks out, there is no need to change something that is working. Play it by ear and be ready to get more aggressive with the AI. I've used 2mg adex ED with 1.25mg letro EOD, to control what would be considered a very high dose of long acting test.
