Research has demonstrated sustained growth hormone release following administration: Enhanced binding affinity to GHRH receptors compared to native GHRH Increased resistance to dipeptidyl peptidase-IV enzymatic degradation Sustained elevation of plasma growth hormone concentrations for several hours post-administration Dose-dependent increases in both growth hormone and IGF-1 levels Studies have shown that CJC-1295 increases plasma growth hormone levels by 2- to 10-fold for up to 6 days, with IGF-1 levels remaining elevated for 9-11 days following a single dose in human subjects
