Expired carnosine,creatine,etc...

[asilaydying]

Found a great deal on some Sartori H bolocker(carnosine) and cexl(cee creatine) It expired this month but was only like $7 for a 30day supply. I picked up 2 of each. How long past the exp will this be good for? Both were very hard powder when I got them, so I had to get a knife and dig though it a bit but now its a fine powder.
