Last friday I did the sedona method and my libido skyrocketed. This only lasted for a short time though. During Sunday I could feel my libido slipping away, and by Monday it was gone again. I took a blood sample on Monday, and one of the things i tested was testosterone, making it the third time I test it. The normal range is 9 - 29 nmol/L (but keep in mind this probably includes what's normal for 80 year old men as well). The first time I tested I got 13.0, which is seems too low for my age, but that was before I started working and had other issues such as vitamin D deficiency. The next test I took (some months later) showed 26.0, which is really good. In fact, doubling the testosterone values are pretty much unheard of. At this point I felt hopeful that I'd solved my low T by exercising and supplementing vitamin D etc. However, the latest results showed a testosterone of 13.4. It's really bad for a young man that does what he can to stay healthy. So it seems like I do have an issue with testosterone, only that it seem to vary a lot. Last few days it's become clear how much it affects me in a lot of areas, not just libido. Last Friday to Sunday my energy was very high. I only slept 5-6 hours during the night and always woke up completely rested. Today I instead woke up after 8.5 hours feeling very sluggish. It's so frustrating when it is like this. Had I always been in this low energy state, then I wouldn't know any better and probably wouldn't suffer as much. But now I know what it's like to feel amazing, yet there doesn't seem to be anything I can do about it. Right now I think the testosterone explanation is the only one that makes sense. I think the reason why other things such as the Sedona method or cold showers can help is because my testosterone is already about to hit the peak, but they help it by giving it a small boost. That's why the same techniques doesn't work when my testosterone is low, even with that boost it's still not going to be high enough for my body to function optimally.
