which Fragrance Strength is the best for p83 and p74?
6% if your going to be layering them.
Stick to the 6% - the 20% is full-on cologne strength and as you are likely to be using these with other pheros, that would get overpowering at only a few sprays.
Thanks 6% it is.. What dosage would be best? im thinking 10 mcg/spray for both in the neroli scent
I take it you are getting a 30 ml? Then yes 10mcg is a good starting strength.
Once you have done your testing and established your dose ranges, it might work out more cost effective/convenient to go stronger.
