Based on your arsenal those are the products I would go for. I think what you would like to test is something like 2:1:1 where P78 is twice to any of the others. I am a bit confused by your IS 2x. If it was normal IS, and based on the mcg of your Togos, I would start the experiment with: 1 spray each.
Hello, thanks for replies and ideas, my IS x2 is from normal bottle, i have normal of bottles for most unless specified as togo or only available as togo.
