It has been for me, in a way its kind of discourageing to me, I am usually up 10 pounds by week six and I am only up 6. Its all good though the gains are rock hard muscle that I know I will gain.
If you aren't drinking enough water you will still retain... I know that from experience, believe me drink 1+ gallons of water/day like your life depends on it!
I give Liquidex to enthusiastic thumbs up for this. I've never used arimidex before... but this cycle I popped for Liquidex. (By the way, my cycle is 400mg deca wk/1200 test wk/50 mg D-bol ed.) For me it amazing. I have none of the usual bloat. None at all. My weight isn't as high as it normally goes... but it is very solid muscle gain... and my strength gains are great.
