Try and keep this short...5 years ago felt bad, Dr put me on 100 mg of Test cyp 1x a week, did ok for a while, HCT HGB got too high, told to donate every 4 months, still didn't feel right, test levels were great, high in fact around 1000, after another year still felt rough (Yes tested for everything, apnea, vitamin def, all kind of tests) cried to my Dr and convinced him to raise my dose to 150 a week, and of course I felt even worse...now lowered back down to 120, still feel horrible, truck ran me over!! thinking maybe even 100mg a week was too much?? I have always had higher estrogen, Dr was never concerned with estrogen. I am thinking I have been on too high of a dose this whole time?? Anyone else have a similar experience? and what did you find worked best for you? I have spoke with a few TRT clinics and they have told me I need at least 150 - 200 mg a week to feel optimal??
