Doctors will tell you that your testosterone level is too low if it drops below 300ng/dL. But in many cases, you don’t need to be a medic to see that there is a problem with your testosterone levels. It's great to have a fitness goal, but getting there can make you feel exhausted and generally low. Bumping your T-hormone levels up with Testrx can help boost those flagging energy levels and bring your motivation and focus back. If you’re feeling low and have no motivation, low testosterone levels are a likely cause.
