So I am finishing week 4 in a Test 500 cycle, by the 3rd week i was really feeling the pump. Strength just kicked in big time in week 4 which i am happy with. My concern is the water retention that i have already taken on. I have gained 15lbs in 4 weeks. I am following a pretty strict diet, but with more carbs than when i cut down to 10.1% BF (hydrostat tested). I still have most of my 6 pack so I don't feel bloated, but I am already noticably bigger according to everyone who questions me at the gym. I upped my AI (liquidex) to .25mg every day but that was almost 2 weeks ago. No sides like acne, itchy nipples etc... From what I have heard, this gear is very strong...and it seems to be. I was just curious if others had initial gains like this?
