not true at all! Normal HRT script from a doc (endo or uro) is typically 100mg/week or 200mg every 2 weeks. 200mg/week is a pretty high TRT dose. 200mg will put most guys around the high end of the range, and probably over. 200mg put me just over the top of the range (990ng/dl, top end was 827). 250mg put me over 1100. Most docs will want to get you just in the range. they should get you at a level where you feel good (libido, etc.) and is within range.
Blood tests support an active life of cypionate ester at 14-16 days, and a half life around 8 days. Ideally, you should be injecting cyp every week for stable levels. Let your doc know you would prefer to shoot it EW and he can cut the dose to 100mg/week instead of 200mg/every other week.
The reason my doc hesitated at first when we were first setting up my TRT to do weekly injects was because he was thinking I would be coming into his office to have the injections administered to me. I told him I would do them myself since I am trained in sterile inj. technique and so is my wife. Plus I didn't want to drive 25 minutes one way every week either.
You should be able to work this out with your doctor too.
