First thing is that you have to have proper expectations that it is going to take a looooong time to get there. You have to be dedicated to being consistent with diet and training for a long period of time. You didn't gain that weight in just a few months so you won't lose it in just a few months.
If you really enjoyed your test cycle, you can always run that again. You don't have to look to add compounds each time you do a cycle. If you wanted to try a combo though, I would do test with deca.
SARMs are going to be much safer on the prostate as they do not have the androgenic properties. That being said, be careful if you have preexisting conditions. Maybe check with your doctor if you want to be sure.
