I was reading an article that said athletes who train hard can have low T due to their body using up the available testosterone. The reason I ask is because I have never taken steroids and my T levels recently were 471, with free test at 11.2 (on a scale of ~ 8-25). However, when I was 19, my total test levels were in the ~900s. I haven't done steroids in the past, so it sort of shocked me to see how low my T levels are now compared to 13 years ago. I would think they would be in the upper 700's, not 400's. The thing I can attribute my low levels to is that I have been lifting consistently and also lowering my carb intake. The day before my lab test I trained arms and did some legs I believe, and also walked around 4 miles. Maybe this had an effect? But that much of an effect?
Any of you have any thoughts or experience with this?
