> I have also done lab work on my sample of sub that is over one year old that was kept in my cooler warehouse.... guess what, hardly changed.
I'd be interested to know what tests you did that led you to believe that.
We know what happens to pollen in storage. I imagine it might test OK, too.
Not saying that this the case here, but products which may be stable when stored as delivered may interact after being combined or after addition of water in ways which are hard to predict.
Lipids in particular are subject to deterioration and can become toxic in fairly short order.
Chemical tests are mere surrogates and give incomplete pictures, since they only tell us what we ask.
What happens in a beehive is what really matters.
I've been wondering what tests, other than actual comparative feeding of fresh and aged to bee colonies of bees can really tell us much since what happens in beehives are very complex.
Although I have respect for lab feed analyses, and their ability to assist us in design, I have strong doubts that they tell us what we need to know about real-world performance with enough certainty to be considered more than just a guide in the right direction.
Also, you mention a "cooler warehouse". Not sure what you mean, what the temperature might be, or how that applies once the product leaves that cool environment, especially when outdoor temeratures are well over 70.
