Just wanted to share for those wondering if testosterone replacement is worth it. I found out I have a brain tumor and it was limiting testosterone due to it impinging on my pituitary gland. My levels were less than 100. I am a crossfit cult member and just thought I was getting older. My legs were always tired and my lifts and endurance were far from what they used to be even though I have never stopped working out my entire life. Once I got on the juice, the sun was brighter, my energy got better and I can go harder than ever before. I was a little sketched out about mood swings and and the other side effects but I have only noticed one. I wake up with a raging stiff again. It has been life changing. If you have low T, go for it.
