As we know PET is very much individualized, but Kyzatrex has that disadvantage of being oral and having liver involvement. You know your body and if you decided to take it, I'm sure you'd have regular blood work done for liver enzyme levels, AST and ALT to check for any liver stress or damage. Let us know how you like it. It would be so much easier to take a pill instead of injections, cream, gel etc.
