Curious to why wouldn't you want to have blood work done? I have my blood work done once a year with my physical. With me, my Doc is running several tests for overall health not just "T".
As for shooting more then once a week; I'm fine with a single shot of 200mg cyp once a week but when I ran 400mg, I didnt want that boost and then have to ride it out for 7 days. Peaks and valleys, no thank you.
