Ok my friend wanted to see what the gear looked like and for some stupid reason he poped the top off not the part ur suppose to pop off cause i already did that becasue i used the stuff already. He poped the part that the needle sticks into, i stayed calm and didnt getmad. I scotch taped it back up so its not loose anymore becasue it wouldnt not go back on normally. I talked to a nurse she said now that he opend it its not sterile. Its my bottle of cyp and i only took one shot of it so far i dont want to discontinue using it. Anyone give me any words of advice or info ?
