CJC-1295 with DAC

Modified growth hormone releasing hormone (GHRH) analog with Drug Affinity Complex. DAC binds albumin, extending half-life to approximately 8 days. Produces sustained GH elevation via continuous pituitary stimulation rather than pulsatile release. Raises baseline IGF-1 steadily over weeks.

Notes

CJC-1295 with DAC is the set-it-and-forget-it GH peptide. One injection per week. Steady-state IGF-1 elevation. The tradeoff is that you lose pulsatile GH release — the natural spike-and-valley pattern your pituitary uses. Some researchers argue the pulsatile pattern matters for tissue specificity. The DAC version gives you convenience at the cost of physiological fidelity. The no-DAC version preserves the pulse. Different tools for different frameworks.
