Hallo everybody. In 2 monts I will start a cycle. Wanted to ask a question about this damn sachets. From what I found there are 3,5 and 20 ml sachets. The 3 ml are bogus. Are the other two OK? Which sachets do u think are better - the 5 or 20ml ones. Help plz. I need sachets cause they are really cheap. Comments please.
