first off let me say that my aunt is a pharmacist so this is where i got my info....i believe that after a drug expires it is still good to take, but its probably just not as strong....like i know its ok to take prescription medicine after it expires its just not going to be as effective....im guessing the same holds true for steroids...on the side though i looked up nabolic and my book says that it comes in 50 and 100 ml vials....and if im correct it says that its only 2mg/ml.....please update me on that...because if its thats true....its not even worth taking....but please let me know
