how can you tell

alrite guys sent pic to steroid pics got feedback saying real,but been looking into other forums etc and they say british dispensary anabol should taste bitter and should not disolve in mouth,well mines dont taste bitter and they disolve in mouth,so how can you really tell if they are real when the tab looks a1 i.e the snake and arrow spot on in detail.also the serial number on the package is a bit distorted.i am holding a fair bit of water on my last cycle but could this just be down to me guzzling down litres a day.
