You going to store it in your fridge? You know with food, and other contaminates, in a cool damp environment with a condenser and fan circulating the air. The same air around your 7 day old leftovers, eggs with potential salmonella, moist vegetables with E.coli, or god knows what else? Then inject it. Sure sterility is paramount, this is 1 additional measure to prevent stupid from continuously spreading across Meso with all you new rude ass retarded opinion people. It's getting old. You ask questions then argue like a disgruntled house wife.
Let me guess you'll rebuttal with I have a private mini fridge for that purpose? Cause if you do why would you argue an additional preventive measure like BAC Water.
