Let's think about it like this. Your body naturally produces testosterone, and not having a naturally occuring substance in your body makes your body not function properly. It's not just the muscle building effects and your boner-ability that testosterone is used for. If you don't have it in your body, it is "impaired".
Test is NOT a must for cycles. But, it is a very good thing to run with your particular set up. Some will say test is a must everytime, I agree and disagree with that.
Perfect, 0.5cc. It's a low dose, but that is okay, It's a lot more than your body produces anyway. With those other things you have, you should cut up really nice.
