I can tell ya this; Powdered shrooms stored in a mason jar at room temp, will lose 40%
potency in 2 months..That's with occasional opening to scoop out a dose..
If you can pack tight n' freeze or remove the Oxygen,like with the honey Tek, then that will dramatically extend it's life..
By comparison ,i estimate that whole mushrooms stored at room temp lose mebbe 10% in 2 months...
I don't understand it. If you grind and put in capsules, then aren't the capsules acting as a barrier to oxygen? Or, are the capsules not really air tight? then put the capsules in a mason jar and seal with a vacuum sealer.
