No, thats not thrue...

Once the cycle ends the endocrine-system will start to produce regular testosterone, even after a deca-only.

Your body want produce any natrual testosterone if you use a test-base either, the only diffrence is that you will replace your bodys natrual hormone with itself, while you are on a cycle.
