customers have no way of knowing whether theyre actually receiving the peptide they purchased unless they pay for third-party testing
Native GHRH(1-44) is rapidly degraded by dipeptidyl peptidase-4 (DPP-4), giving it a plasma half-life of only minutes
However, most evidence comes from animal models or small human trials
