A correspondent sent this message:
Chondroitin sulfate and many other GAGs have been patented from decades to “prevent and cure” HIV. And to serorevert people… Interestingly enough is that Jean Claude Chermann, one of the “discoverers” of HIV, is one of the guys who signed a patent… These facts are pretty well known in the field. And kept well hidden for obvious reasons… Please spread the word and feel free to contact me for any need.

I also found some articles in journals about these possibilities
