Very doubtfull. The expiration date on pills is about the same as the expiration date on beer.................not very significant. I have taken pills with an expiration date a year past and have had the same results as "fresh" meds.

The pills the poster described as 1mg Xanax sound more like 0.5 mg Xanax. I can not say this for sure as I have not seen or heard of a description of the pills. Usually, from overseas pharmacies I receive blue (football shaped) 1mg tablets branded "Tafil" or purple ones of the same shape and different brand. Always in blisters.

I have never received any Xanax colored the way you described from any OP, domestic or international.

Maybe include a more descriptive explaination of the tablets. (color, shape, markings, blister packing indications.)

PM me if necessary.
