duretics will f**k you up condition wize if you dont know how to apply ( timing and dose,,)
you need to know your body inorder to use duretics because it can and will flatten your muscles while taking the water out,,so you will be with no h2o but yet you will look stiff and flat,,
if you count only on duretics excessivly,,and some do,,with out dieting and using other methods to lose some of the water,,,your kidnys will suffer,,,some kidnys can suffer long some can not,,,the strong survives while the weak retires,,
in general i wouldnt count only on duretics to do the final touch,,
