If you take your exercise and supplementation seriously, water retention is something that just seems to go along with it. Pro bodybuilders have used diuretics to get that ultra 'tissue thin' skin look. When the water's out-- vascularity is in! Who wants to look like a human water balloon anyhow? Now, you can have that prescription potency without those 'rough on your system' side effects. You want to lose the water and not a kidney, right?!
