Any ideas on this. I was on Test E for a while and was doing 160 every 6 days. Total T was around 650. I was feeling pretty good, only issue was symptoms of high E, E numbers were high but only borderline. Well after seeing specialist I went onto Test CYP. 100mg e6d. Just got tested and I was 550 something, with no signs of high E, but I dont have numbers. But overall I dont feel as good as I did on test E. How is it i could take be taken 60% less on CYP virtually have the same numbers but not feel quite as good. On Test E my libido was crazy, I was walking around with a 24/7 wood, which was getting annoying. I asked doc about bumping up the CYP a little and they said no as they treat to middle range. But I have an appointment in a month in person and going to convince them to notch is up a little and I think I would be perfect, and or if if I keep collecting the stash of extra I have lying around I should be able to go up 20mg myself here shortly. I had an MRI and pituatary is fine. Going to URO in two weeks to check and see if my nuts are the problem and to talk about an Human Chorionic Gonadotropin (HCG), which will that help. Just wondering why CYP i have to take so much less to achieve the same number results as E
