Gloss optimizer shelf life

any thoughts on this? I have an untouched bottle several years old, have some tests I’d like to try with it, wanting to keep costs low just for tests… I have used a lot of inks passed recommended dates without problems, with effort put into undoing setting. There’s no pigment particles in GO of course, but just wondering if there is any reasonable concerns to trying it out, even though I realize no manufacturer is going to undermine their own usage guidelines…
THanks,
