Junky it stays as stable as regular concentrate so I would expect a normal decrease over time. Yes potency is immediately less than the concentrate starting material because it is diluted, but instead of dabbing you can just puff puff away with a vaporizer or add some to the top of a bowl of bud. So really it's just a different method of delivery. I keep mine in a syringe and squeeze it out bit by bit. Doesn't stick around long when I make it lol.
Now in a tank the material may degrade faster because tanks can get very warm with use. So I have tended to use mine with a dripper and wick. That way I just use a syringe to lay some on the wick and vape it all. Then reload.
Sounds rather simple enough. Yeah, I figured to some degree it would get diluted but just wasn't sure how much. Thanks for the details, sounds at least worth trying out this form of delivery. As the person that would be taking it would be trying to utilize this to reduce their dosage of Percocet I feel that it wouldn't last too long anyways so all good on the degradation factor.
