Dutch pro boost, maybe expired date

Bought this bottle around 18months ago, theres no date on the bottle anywere atall, the liquid is still clear and doesnt seem to have any unusual smell/look to it.

Im unsure if its still ok to use, if its out of date would it cause any harm or would it be alright. Its quiet expensive so if i can use without having to replace id rather that

Doesn't say organic, should be good.
