Those of you trying to save money by grinding up spironolactone pills to make your own spironolactone topical:
It is most stable at a pH of 4.3. Without pH paper, it is hard to know how much lemon juice to add to make it 4.3. Vitamin C buffers at 4.3, which means if you put put some in, you got a good chance of getting close to 4.3. But vitamin C is not stable, and may break down in a week, according to some sources (not sure how drinks get around this). But alpha lipoic acid is cheap and buffers at pH 4.7. That should be close enough. 5% ALA creams are also very good for your skin. I'm going to make a skin cream with mine, and put some in my topicals.
