An old topic , but just an update that I have been using Aldosterone for 4 years and it definitely increased my blood pressure. I was dizzy on standing before I took it but most of the time I'm OK now. Also for those of you questioning whether you need Aldosterone, rather than just taking a precursor hormone, in my case I have to be very careful of the hormones I take as I have had estrogen receptor positive breast cancer, so I have to avoid hormones that can raise my estrogen. Aldosterone is perfect in my case as I just need my blood pressure raised - I don't need any other hormone effects. I'm in Australia, and Australian doctors will prescribe it and there are now Aus pharmacies that will compound it. pm me if you need the details
