Okay, so the most important thing concerning water retention is aromatization of testosterone into estrogen. The ratio of testosterone to estrogen is what determines how severe your chances are for developing serious estrogenic affects such as gyno. So what do you do if you are one of the unlucky few who are susceptible to gyno? What if you just want to use strong drugs but don't want the water? What if you are prone to "potato" head syndrome and seem to bloat up no matter what? Your answer lies in proper use and understanding of anti-estrogen and anti-aromatase drugs.
