I was simply saying that cause of the high BA content the 50ml bottles contain compared to the 10ml. i know QVE004 had extreme pain with the 50ml bottles. Higher BA = pain/flu symptoms for sure. just bake it,filter or whatever and its should be fine tho. as far as potency goes i would think they r the same. good thing with the 50ml bottles is it is such a damn good deal. Has anyone tried the 50ml bottle of deca200. if so was it good or bad ? thanx BTW -the BA content is higher due to the extended shelf life for the product i beleieve since it is a bigger bottle it will take longer to go through hence the more BA
