RU has still not been proven to be safe. Who knows what kind of systemic absorption would occur and what it would entail. I'd rather stick with the tested substances.
Here's something on this issue that I posted recently on another hairloss site:
-----------------------------------------------------------------------
For a few days now, I've been fretting over whether or not to say anything about this. I didn't want to alarm anybody unnecessarily, but now I feel a duty to report this in a simple journalistic fashion, because a growing number of people are now using RU. The following statement was made by Dr. Hideo Uno in a recent email to my friend TAGOHL (he posts on hairsite)...since TAGOHL himself posted this recently on hairsite, I feel it's ok to post it here, too:
"RU58841, topical formulation, is not entirely safe; if application continued too much, anti-androgenic effect appears. This was done in pregnant rabbit, topical application of RU58841 produced demascularization of pups. No data available in male pattern baldness human. My studies on monkeys showed no shrinkage of the prostate (by MRI) but reduction of lobular size occurred in the seminal vesicles."
Needless to say, I'm a bit surprised by this statement. The available studies on RU58841 (trust me, I have almost ALL of them) show very little systemic side-effects from topical RU58841. But Dr. Uno seems to think that it _may_ produce systemic effects, if the dose is large enough. My purpose here is not to alarm anybody, but to make sure that we all know as much as possible about this drug...

Bryan -- do you know of any studies on RU pending or forthcoming in this regard?
No, I sure don't. I generally only catch wind of them after they come out, and I spot them on PubMed, or as a reference in another study. If any of you find a study which looks interesting for us male pattern baldness sufferers, by all means send me the citation and I'll add it to my "Get List"!
