Getting older sucks! It seems like my body constantly aches, continuous issues with my back, energy levels suck. When you work extremely hard one day, you feel it for days on end. It's becoming difficult to deal with. A few years ago I was diagnosed with low testosterone, very low testosterone. This is a naturally occurring issue for us men as we age. I started testosterone replacement therapy and actually had a doc that believed men should be at the high "T" levels and not just within range. So, he brought my levels up to around 1400. It was a night and day difference on how I felt!! I dropped probably 20lbs and had gobs energy. It literally made me feel so strong to the point I had to exercise my muscles because they craved the attention, the abuse I could give them. It did cause aggression as well. But overall it was the best thing I had ever given my body. I looked and felt like I was 20 again! However, it was extremely expensive and I was paying out of pocket, so I didn't stick with it. It's been on my mind a lot lately how crappy I feel all the time so I've made the decision to start testosterone therapy again. If you're feeling this way then I'd urge you do some research on low testosterone. It can change your life.
