Your likly to get less water retention with sus than some other test esters, but when you get up to around 500mg a week or higher you will get some bloat from any test. Water retention tends to raise bp. To help combat the bloat take .5mg of arimidex a day. Also do a search on diuretics, to rid your body of excess fluids, this may be an option worth considering. In most cases arimidex will do the trick.
depends on your dosage, also depends on the individual, i did a test/dbol/fina cycle without arimidex and my bloat was very mild almost unoticeable...like i said its on an individual basis
