Bought it a few months back but realized I prefer the ECA stack. Only used a few scoops of it. Due to leaving it in my car for a couple of nights the humidity caused it to chunk up a bit instead of being in a fine powder form. Nothing that a spice grinder couldn't fix. It still dissolves in it's current form, just takes a little longer. I really didn't want it to go to waste so it's up for grabs if anyone wants it.
