hey rock after i answer your question delete this thread, no partial emails are allowed when it comes to a source. if your worried about sterility , all you have to do is bake it in an over at 250 for 10 min, take it out and let stand for 10 minutes. repeat this process 2 more times. generally it should be sterol,. ask your source what kit he uses and what precautions does he take on making it for sterility.. fina is easy to make and sterilize..
