Old unused finastrdebottle from lee, is it still potent or decayed somehow?

Hey, Long time, no see :wow:

So i got 2 bottles of OLD finastride. Probably around 1 - 2 years, unopened. Is it as safe to take them as any other finstride, or is it decyed or something so its more or less useless to take? The bottles are not exactly airtight

They may not be as effective but I would probably take them.
