Expired Test-Enth?

Im about to finish my 4th week and have realized that I will only have enough test-cyp for a little over 8 weeks, I have about 13 vials of some Iranian Test-enth BUT it says on the vial that it expires 2009.
My questions are, will the expired test still work or is it no good and if it is good can I use it when I finish up my T-cyp?

Thanks

any help?

It’s probably degraded but not totally bunk yet. Maybe up the dose.
