OP,
If your bw was done soon after your shot, it's not surprising your level was at 700.

A shot every two weeks - whatever the dose - indicates clearly that your doctor is incompetent regarding TRT. I'd suggest you find a new one. Weekly, twice weekly, or even more frequent injections is the norm. This or it is guaranteed you will continue to "feel like shit".

However, at your age I'd advise that you have the goal of getting your natural production of testosterone back. I would hope you have that goal. I'd strongly advise you find a physician who knows what he's doing so you can get there.
