I ran all three because I have the money, and I want my balls to come back full power. I got a blood test and it came back good Total test was 998, just want to make sure its all good, because my getting erections takes longer now, I can still get them, but they are not as hard as quickly as they used to be. My sex drive is great though, maybe some cardio and better eating is in order, get those blood vessels working better.
