I think cb something is the best, but I think it's very expensive and only in research stage so hard to get. Same for RU. But I think more people do get a hold of RU. Azealic acid maybe it works but it's inexpensive. spironolactone works for more people but expensive like 30 bucks for only 2 oz. Yeah you read that right. The peptides I don't think help as many people I havent read alot yet, but you can get it at the web site.
Maybe someone else can chime in. I'm searching to for something that is said to block dht's affects on the hair follicle.
