Then why are so many docs saying every 2 weeks?

I am starting to feel the same way as bpt513. I have just had my 7th injection (2 week intervals) and have been feeling better. But for some reason, after this last shot, I have not had the typical swing to feeling good for about a week to 10 days. I'm just 4 days post shot and "off". It's like this last one didn't work as well.

We did bloodwork before the shot 4 days ago and I'm curious as to my levels. My level check at the 1 month point was lower that before I started TRT.
