i have a few questions and this is one of\'em:
i\'m not exactly sure why you need to mix the phero\'s. if androstenone is what you\'re after, why buy anything that has less than the highest concentration? wouldn\'t mixing pi with just about anything dilute the overall strength of it? even if you mixed it with andro 4.2, let\'s say, it would lessen the effect of pi. i don\'t know why anyone would use anything other THAN pi, since it\'s got the highest concentration.
