Out of 6 months of researching LDN before allowing my son to start using it, I have been told over and over again on the 3 message boards that I utilize that it is extremely important to use a compounding pharmacy that has a good reputation for compounding LDN properly. (We also use Skip's) I've seen way too many postings about filler problems and compounding problems for so many different people. Skip was really helpful to me when I started this quest for information, so I felt a bit of an "allegiance" to him when we finally got the script in our hands!
I have a friend who used the same doctor we did for her phone consultation. When he recommended the pharmacy there in his building to her, she agreed. She received her LDN with calcium carbonate filler, and immediately began producing calcium kidney stones, much to her dismay. In saying this, I am also warning you to take the filler used into consideration, as well. While calcium carbonate might not be a problem for some, it was for her. She is now awaiting a script from Skip's, which is the pharmacy she wishes she had used to start with!
