A Study on Plasma Blood Levels of Sust250

I was reading a whole bunch of threads previously and Im not sure if it was this forum or another, but I came across a study done on plasma levels of sust250 throughout the week.

Im curious in trying to find this study as I mostly read/hear that sust is not a good choice as T levels dont hold stable due to the different esters.

I can get pharmacy grade sust250 but only UGL test-e.

If anyone knows of the article, thatd be a great help, thanks.
