I don't know about peptides but I do know a friend from another health group went thru a year of peptide injections out of a doctor in FL. She dealt with sjorgens and arthritis and fibro issues. At the time these injections were about $300 a session and she did 12 or more.

I'm into 3rd month with UCII collagen and have good results and Scripps San Diego just reported on clinical trials after 180 days of using it on people. I'm into 90 days now. This may not interest you but it's the collagen I am taking now.
