Back when I was cycling, I did notice that I seemed to feel really good (no, EXTRA good) the days I used Human Chorionic Gonadotropin (HCG), even though my serum T levels were several times the top of normal range. I especially notice it now that I am doing Hormone Replacement Therapy (HRT). That's why I like my guys to use it on the weekends (they like the extra bump then!).
