Well for me… I try never to mix in a bottle any of the consumer products. These are mixes with a purpose and doing so just throughs off the ratio of of Pheromones.
I usally pick one or two primary mones like Bnol and Copulins (which are my favorites) and steer them in the direction I want to go with the putatives.
I usually keep it to about 4 to 5 pheromones because you really need to understand what each molecules does and how it plays off other molecules to make a good mix.
Before mixing I always layer the molecules I plan to use to make sure it will have to effect I am looking for.
Then I test test test on myself and other test subjects to be sure its consistant.
