I used to be able to get it at Alldaychemist.com, but lately it has said they are out of stock. So I went another route and it has worked well. I got on Ebay and found some koi aquarium prazi in a white plastic jar. I then went to our local nutrition store and bought empty gel caps, size 00 and filled them. This is very tedious, but it saves you a ton of money. Go to ICU's protocols and read about this.
