I bought 3 bottles of Syntherol in June 03 and i noticed the date on my 2 syntherol bottles says Jan 04... is it useless ,can it be made useful or am i out 2 bottles?
It's up to you, but you are running the risk of the oil being rancid.
BTW, where did you buy it from? Synthetek moves so much Syntherol, when you would buy it, the expiry date is 2 to 3 years away, not just 7 months as with yours.
