Aldactone is a diuretic used for the shedding of excess water, particularly before a show.
Aldactone active substance is Spironolactone.
This is probably the best known diuretic used. It is more dangerous than people realise, if people would only read the packaging or inserts they would know this. Aldactone is known to cause tumours even at low dosages.
Three dosages are available, as far as I know, These are 25 mg, 50 mg, and 100 mg.Aldactone causes excretion of water and sodium and because it does not excrete potassium it is known as a potassium sparing diuretic, and because of this potassium supplements should not be taken with it, so watch the bananas. If your diet has a lot of potassium in it you will get a condition called hyperakalemia and you will have a heart attack. OK I know you are a super fit bodybuilder a veritable superman and invulnerable, but you will still have a heart attack.
Aldactone must be taken with food or it will not work, it also increases the effects of other diuretics. Aldactone can also cause gynaecomastea (bitch tit).
I reckon this stuff should only be used under medical supervision.
