I wouldn't say I've seen any particular results, but I've been using a number of different things so it's impossible to attribute the results I've seen (mostly maintenance, some regrowth) to any one particular source.
That said, I think toco-8 helps form part of the puzzle - any successful attempt at telling hairloss to go f-itself has to approach from as many angles as possible... toco-8 is just one angle of attack in my honest opinion.
I've been using it for about 4 months now by the way, and will continue to do so as far as possible... actually to that end Pp, do you intend to stock this stuff at nutra because that would make my life much easier!
