Welcome to Pherotalk Alan!,
It’s good to see that you already have some experience and that you are into experimentation 
Since you already have products the best advice I can give you is to follow this guide on how to find your Sweet spot (the number of sprays that works best for you) by Steve. This will help you get your best results:
How to find your sweet spot... (How to find your sweet spot...)
BTW you can PM Steve so that you can join the A314 insider’s club if you haven’t already
Hope to hear about your pheromone adventures soon
