CJC-1295 with DAC is studied to work through three linked routes that keep the growth-hormone signal switched on longer.
It binds the GHRH receptor on pituitary cells, the same switch the body's own hormone flips to trigger growth hormone release.
The DAC group latches onto albumin in the blood, shielding the peptide from breakdown so it circulates for days instead of minutes.
Sustained growth hormone release drives the liver to produce IGF-1, the downstream messenger researchers track to gauge activity.
For research use only. Mechanisms described reflect published preclinical and clinical literature.
