Using RU in a KB solution (5% concentration, i.e 50mg/ml from @nageni**). Not sure whether it works as I am on topical finasteride, lipogaine + azelaic acid - all 2x a day. And occasionally say 2x a week I use an S5 cream as well. Was shedding a lot past 3 months, now I can see plenty of small hairs in my frontal regional popping up. All I can say I do not get any sides, perhaps very light ones but that could also be from finasteride.
FYI, Genh@ir topical finasteride was really good and thickened my hair really well. But since their shut down I need to prepare my own topical finasteride. GenH@ir now operates again under a different name (just google GenH@ir) and see what kind of bull**** they are selling now :wow::wow::wow:.
