Intermittent use has always worked well for me. Cant wear it all the time or the effects diminish. Also i dont believe entirely that the only effects are hormone related. Your body acts as a battery and these dissimilar metals as the anode and cathode. The electric charge def causes a change in blood flow. After a heavy PE session i notice a quicker healing cycle. Balls got bigger etc. The purity of the zinc is what matters as these ions are what will be travelling thru your body. The copper is what produces the galvanic potential. If you have low zinc level you will notice a change. If you have optimal levels likely less so. Theres alot of research out there of holistic benefits of micro currents thru the body and healing.
