i really want to start using minoxidil. since im a poor bastard im going to go with the generic (walmart) brand. but is it the same as rogaine? i dont see how a generic could have a different amount of minoxidil but i keep seeing people say "its not the same" and make claims like "generics are allowed by the FDA to be off 20% in potency." I certainly hope thats not the truth haha.
