Tweetno shit you're noticing some swelling; what dosage is your liquidex, is that 1 mg/day of arimidex?
you'll probably notice swelling in your feet, ankles, wrists, fingers, glands in the face and generally anywhere you have muscle.
What's the reason for "upping" the test to 1600 mg/wk. There is a definite point of diminished return when it comes to gear. I don't see why you need more than 1000-1200 mg/wk at most; unless you've used it to the effect that its effects aren't potentiated anymore.
