Watching these boards so long I notice a lot of guys that use aromasin still test high estrogen. I don't know if there is a lot of bunk aromasin out there or the dose is to low or the timing is wrong or what. Other issues can cause water retention like yours. Paying the 150 for bloods at privateMD or the like is not a bad idea. AAS can through off your water balance other ways besides estrogen like interfering with mineralocorticoids like aldosterone and also corticosterioids. Personally if I cycle I try to keep the compounds on the drier side. I would use a lower end test base with one other inj low aromatizing compound and a mild dry oral like win, t-bol or anavar. Maybe super dmz or epistane also ok choices. Drier inj could be primobolan, masteron, equipoise, test-1-cypionate or even NPP. A good mild drier cycle with minimal sides might be something like:
test C 300 mg
test-1-cyp 300 mg
T-bol 30 mg/d
adex 0.5 mg ETD
This would be mild but effective for me and little water retention. Also limiting carbs reduced water retention.
