I still bloat with very very very little sodium and 100mg test prop eod. Bloat from AAS has little to do with sodium intake. Yes, eating very low sodium and drinking tons of water will keep you from getting even more bloated... But him bloating from testosterone is directly related to estrogen.
For me, there is a significant difference in my water retention when I lowered my aromasin dosage from 12.5mg eod and 6.25mg eod. I still bloat a little at 12.5mg eod, but not much at all. I've noticed at least a 2-3lbs difference when I dropped to 6.25mg eod. So I always keep it at 12.5mg eod. Pretty much same for me with arimidex, .5mg eod is the magical dose for me to keep 90% of water off.
