This is correct. I have used the sterile water and stored it in the fridge for weeks. After the 3rd or 4th week I started noticing that around my belly button some welts started appearing and I did not know what it was. Once I would start a new amp of HCG they would slowly go away, but after that period of 3 or 4 weeks there they were again. Had not such problem with BW. My guess is that I was having sterility issues.
