BRO!...Aldactone is an androgen receptor antagonist... do not let her use it even if she is on roids......better choice is dyazide. Do a search on the net for the dose used to control hypertension and then take half that daily.
She could also try dandelion root as it does work a bit.
Sorry but I respectfully disagree.....not when you are at a high level of comp .
But I don't know why she wants to use diuretics as not enough info was given.
