Yes, if it doesn't have a retest certificate elsewhere on the bottle it expired 04/2011 and needs retested. Some of the Procaps tanks had a 3 year hydro as well, but either way this one is in need of testing.

Yea and rehydroing costs anywhere between $20-$30 usually depending upon where you go to get it rehydroed and where you live so overall I think you got a good deal there
