If anything the potentcy has dropped maybe 20%. I have heard after 2 years past expiration date the medication declines around 10% each year. so probably 10%-20% loss in strength wich still puts them at about 40-45mg per tab. I have taken expired medication before and it worked it was about 2 years expired as well(blister sealed just like that). The question is were the pills dosed correectly when you bought them? I can't make out the manufacturer. You will know right away with potent anadrol you should feel those in 2 days at most. Huge pumps a little high blood pressure and you know they are legit.
