Since it was used once, I would not use it. 2 years is a while and bacteria is incidious, that stuff never quits. But I am MR careful when it comes to risk for infection, got one once and that possibility scares the crap out of me.
You may or may not get an infection.......more than likely not............but is one lousy bottle of EQ worth the risk? Whats it gonna do anyhow? You need a couple bottles of the stuff for a cycle, just get some freash gear.
