It is a lot less interesting then mod GRF(1-29). It is inferior to what you have available. Nothing will surpass the ability of the things you have now to squeeze out all the GH you have available which regenerates and 3 hours later you do it again.

Pharmaceutical companies just patent all kinds of things. Tes is plain old GHRH w/ one amino acid mdification.
Mod GRF(1-29) has 4 amino acid modifications.
