thylax said:I found it today. Just take your rogaine bottle and throw in 20 tablets of aldactone. Its very cheap, just 1.8 euros/20 tablets. Shake well. Wait a while and then open the bottle. You will not be pleased with the spironolactone smell but you will be sure that you have your own minoxidil-spironolactone solution!
25mg/tablet *20=0.5 gram of spironolactone in 60 ml of minoxidil solution -->
0.83% spironolactone
