The key to keeping down bloat on compounds like Deca or Drol is all about controlling diet and salt intake. IDK if diuretics would help.
I agree w/ you about contolling sodium levels while on cycle to keep the bloat at bay, but using a low dose of adex will also aid in this. No need in using diuretics especially if not competing, but using green tea on a regular basis can display diuretic properties.
