my experience over the last few years has been that some pheromones have to be used in certain amounts to get a reaction,
and some differ in amounts based on your own natural signiture.
since this is one made naturally during pregnancy, my guess is that the amount used should be fairly consistant.
unless most of us are already pregnant here ? 
it took me till about 62.5 mcg till i saw hits that counted.
my sweet spot is around 100mcg,
with that i see the vibe in the room get raised and people are more kind/loving.
you may have a different experience, but if you do a search, you will find others using higher amounts safely if your already feeling like you want to up the dose some.
