5% spironolactone cream is the strongest heavily proven topical anti-androgen. RU58841 is 10 times as strong as spironolactone, but little research has been done to find the best delivery vehicle. Right now people just use 50% alcohol, 50% PPG and get good results. If you could get the same concentration in your scalp as you have DHT, alone it would as strong as proscar 5mg. But I have not seen any estimates at how much gets down in there.
The cream is much better than the liquid because it does not dry, and keeps sending more spironolactone into the skin for hours. spironolactone gets metabolised into a much weaker anti-androgen, and looses its effect that way when it is a liquid, especially after the liquid drys and stops putitng more in.
Eucapil has not been tested by people other than the manufacturer and the scientists it hired. I think fluridil is stronger than both flutamide and the stronger metabolite, hydroxy flutamide, but both of those are much weaker than spironolactone. The nice thing about fluridil is it evaporates in less than a minute and you only have to apply it once a day. Twice a day is not better. I have some. The applicator was hard to use, so I just poured it on my head. The 2mL can easily cover the front of your head.
Yeah, I agree about the minoxidil. It increases hair weight 30% while you use it, and you loose all that very fast when you stop, and end up where the placebo is without minoxidil, like you had never taken it. It is a bit anoying, so if you want to keep what you have, you don't really need it, and if you want more mass, definitely use it. I do think it does protect blood vessels somewhat, and works synergistically with CP's for preventing some damage or stopping some attacks. I use it for that reason. I think the 2% is just as effective at that as the 5%. I just dilute the 5% 50-50 with rubbing alcohol and add a tiny amount of flax oil to prevent drying.
