CJC-1295 No DAC versus CJC-1295 DAC in research literature
The DAC (Drug Affinity Complex) variant carries an extra moiety that binds plasma albumin and extends the serum half-life into days. CJC-1295 No DAC, by contrast, has a short serum half-life — commonly cited at approximately 30 minutes — supporting research models that investigate pulsatile, physiological-style GHRH-receptor stimulation. Most modern research protocols favor the No DAC variant for that reason.
