What is the difference between CJC-1295 with DAC and without DAC?

CJC-1295 with DAC has a Drug Affinity Complex that extends its half-life to 6-8 days, producing sustained elevated GH levels. Without DAC (mod GRF 1-29), the half-life is about 30 minutes, creating more natural pulsatile GH release patterns preferred by most users.
