Nope. they were the original drugs developed by Allen Allen (his first and last name were the same). He founded the company and stepped back when Nader joined and bought Pro 140. Pro 140 had some grant $ so it had a better chance of development. Not sure what was the difference between pro140 and Cytolyn, but Cytolyn was put on a shelf. Cytofeline was a hail mary modification of Cytolyn to try and get something approved to get revenue by going after the vet market for cats with HIV. I'm not making any of this up, BTW
