People love Patrick Arnolds topical 7 spray (topical 7-keto). I'd imagine most of the effects saw from using PP's AndroLean (v1) were from the 7-Keto, and I'm know their using it again in v2 along with 11-KT (WHICH IS SICK!!) and dropping the 5-DHEA (thank god). Taurus Nutritions topical 7-keto always got favorable reviews. So I'd say there's something to it.
