i used an expired eye wash bottle i had in my first aid kit (active ingredient .9 sodium chloride, inactive ingredient: sterile water for injection) Expiration 2014
i used 1ML in 10iu vial.
i did 1.5/1.5 yesterday. 1.5/1.5 today. it's not bad, just tender. no lumps or anything...
i did order a bacteriostatic water, but i was too impatient. i should have it by Monday.
