I made my fina about 3 weeks ago and i intend to use it at the end of my cycle in about 6 weeks. here's my question. at the bottom of my vial there is brown residue that is stuck there. it kind of looks like a ring of coke that was imprinted by the bottom of the can on a table.
i stored this in a cool, dark place.
i tried to put it in hot water again but i just stays the same
is this normal or did i lose a significant amount of fina.
thanks
