A314 definitely has a little amount of Androstenone in there but is predominantly Androsterone with a number of other components (the latest version includes a total of 16 pheromones I do believe). Michael Harris from Androtics has posted on the problems of using -Rone alone and why a little -None needs to be added to it (see below)…
MHarris:
"I know what you mean. Androsterone by itself has some serious issues.
I tried more closely to formulate the new A314 to the James Bond character (I’m sure it was in the back of my mind previously, too).
The experimental mix that ended up being A314, the one that “made it” in the tests, was based along the lines of something like a transmogrification of 80/20 principle… except the 80% part really does do something. The 20% wouldn’t exist as effectively without the 80%.
Nonetheless, that 80% [Androsterone] part is safe, perhaps too safe. That’s where the other 20% comes in to play, and IMHO, is essential.
I would never use Androsterone completely alone. It has some serious downsides. I’ve never liked the effects I’ve gotten from wearing Androsterone alone…"
MHarris:
“…A314 is highly refined -rone] that doesn’t put out the “Walk all over Me, I’m Mr. Rogers” type prescence that Androsterone alone can sometimes do on some men.”
