I have been on hrt for 5 years and im prescribed 200mg of cypionate a week and my levels on the 7th day are around 750.Now some doctors measure peak and others measure trough but alot of doctors want you to be in the upper 3/4 range for your testosterone levels,that means checking your levels at their trough.I have had no problems at this level for 5 years and i am very happy with that dosage so T.O.M dont let anybody talk you out of taking 200mg a week.You can be healthy at that dosage without any problems.
