Gave ever calm a try many years ago and I cannot say it did anything.
About a dozen or so years ago I put out a doe decoy with some VS-1 on it and left it out over night. When I came back the next morning it was down for the count.
I have completely given up on all scents now. Since 08 I have been using a scent elimination spray that came from an Outfitter in Ohio. Baking soda, peroxide and water. My hunting clothes get washed in baking soda and bagged. My street clothes get the same treatment as does my towel but separate from the hunting clothes.
The shower consists of a solution of baking soda and after I am towel dried I spray on the scent elimination spray, my entire body gets coated in it. I brush the teeth with baking soda and gargle with the scent elimination spray. I never wear my hunting clothes on the quad or in the truck, they remain bagged until I get about one hundred yards from my stand. Then it is strip time and spray down again time. Nothing like being naked in the woods on a 20 degree morning and then spraying yourself down. When this is done I pull out the hunting clothes and put them on and walk slowly to my stand trying to avoid sweating. I continue to spray down throughout the day as well. I swear it almost makes you invisible to the deer, it is as if they think your scent is older then it is, or that you are farther away then you really are.
