Forgot to purge after kegging

[Helga]

I corny kegged a batch of 2 week old Alaskan Amber 4 days ago and forgot to purge the air when I hooked up the Co2.
I did run about three glasses of beer through the tap and lines after hooking up the CO2.
I have had the Co2 at about 15 the whole time.
Is my beer hosed?
Will I be saved by the co2 blanketing the top of the beer?

Thank you in advance for any help/comments that come my way.

It'll be fine. Most of the oxygen was probably pushed out when you racked it. If you are concerned, just drink it faster Oxygen takes time to ruin beer and so do creepy crawleys.

Thanks for the reply. I feel much better now.

+1 to what DB said, plus if you're still worried about it, you can still purge it, repressureize, purge, repressureize a few times and be fine.

Relax it will be fine. C02 is heavier than oxygen so it should be blanketed by that. Not to mention a full keg only has small amount of headspace in it.

Cool. I did purge earlier tonight hoping it would help.
