CJC-1295 (with DAC)

CJC-1295 conjugated to a Drug Affinity Complex linker that binds serum albumin, extending half-life to roughly eight days and producing a steady GHRH-axis baseline rather than pulsatile peaks.

Documented pairwise interactions

  • warning

    CJC-1295 (with DAC) + CJC-1295 (no-DAC)

    Short-acting and long-acting forms of the same GHRH analog; combining the two stacks receptor stimulation without literature support.

  • caution

    CJC-1295 (with DAC) + Ipamorelin

    Long-acting GHRH paired with a short-acting GHRP — frequently co-investigated; ensure GHRP dosing remains conservative.

  • warning

    CJC-1295 (with DAC) + Tesamorelin

    Both are GHRH analogs at the same receptor; the DAC long-acting form already maintains baseline stimulation.
