On the 10th of June 2015 I picked up my t3 and the BN was 82613 and expiry date 16.06.2016. 8 weeks later and my next lot of t3 and the BN was 83200 and expiry date was 18.02 2016 and my new lot has BN 83200 and exp date as 18.02.2016. Would anyone know why the 82613 would have a later date then the 83200. I think this happened once before. I am beginning to think that any old pil is put on the tub of t3.
