It's very well known that Spiro comes with the energy-robbing effect and also because your T levels aren't of a man's levels anymore, more likely it won't return to "normal" anymore. Those of you are still sleepy and dragging around, please look into trying coq10. It's present in every of our cell but decreases with age. If I take more than a certain dose, I won't be able to sleep so that's how I know it works.
