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.
Anabolic processes tend toward "building up" organs and tissues . These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules . Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass. Endocrinologists have traditionally classified hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The classic anabolic hormones are the anabolic steroids , which stimulate protein synthesis, muscle growth, and insulin .  The balance between anabolism and catabolism is also regulated by circadian rhythms , with processes such as glucose metabolism fluctuating to match an animal's normal periods of activity throughout the day.
