Results pretty much similar buckthorn. One might be a little better than the other, that's all.
Yeah I agree with you, it is sh*t but PRP is backed by studies man

. See here for instance;

Ken Washenik is the principal investigator of Kerastem btw. He will do everything for the $$$. Even if that means being the medical director of Bosley (hair mill, responsible for butchering many people as you know personally) Promises left and right with aderans but got nowhere.. Could barely admit failure with aderans.
Histogen, pretty much a laughable company. Started back in what 2007? 10 years, later she got sh*t besides launching her cosmetic growth factor line. She got ridiculed heavily back in 2012 at a conference by many people when she finished her presentation. People were outwards rude to her and laughed in her face. She never changed presenting her results. Has Ziering as her principal investigator. The guy runs a hair mill. Look man;
http://www.dailymail.co.uk/news/art...alding-men-transformed-having-heads-hair.html. Misleading people to the fullest. Google furthermore "Ziering medical lawsuit." Again promises left and right too from the mouth of Histogen.
Get the picture?
Ken Washenik seeing the $$$;
