I have heard from this site that people seem to have less side effects on the Forteo than Tymlos but when you read about the two on fact sites it says Forteo has more side effects and is a man made peptide, where Tymlos has less listed side effects but is a natural occurring peptide - so I though it may have easier reaction on the system but so many people seem to be suffering on Tymlos vs Forteo - both harsh but just what I am reading - have you any thoughts on this as I am trying to decide which one to start.
