Is old primal more effective?

[**DONOTDELETE**]

Hello everyone,
I was checking out the Love-Scent\'s Forum Members club, and I saw that they had the \"old PI(m)\" listed there. And they have some interesting combos with the Old PI.
What\'s the difference between the new PI(m) and the old one. Which one has a higher concetration of pheros?

thanks for your help

I would like to know that also. I have 2 different bottles of PI. One bottle have a round silver label on top and the other without label, but with an extra note \"PI 5.0\". Does someone know, what this mean?

The new version is more concentrated i think or its a different cover scent.
Still worth checking out though.
