Stacking
GHRP-6 + CJC-1295 (Mod GRF 1-29)
This is the classic GH secretagogue stack and the most widely used combination. CJC-1295 (without DAC), also called Mod GRF 1-29, is a GHRH analog that activates GHRH receptors on the pituitary. When combined with GHRP-6, the two compounds activate complementary pathways: GHRH primes and sustains the GH release signal while GHRP-6 amplifies the pulse amplitude. Preclinical and clinical data suggest this combination produces substantially greater GH elevations than either compound alone, though the precise magnitude has not been characterized in controlled human trials.
A typical protocol involves 100 mcg of each peptide administered simultaneously via separate subcutaneous injections (or reconstituted in the same syringe), two to three times daily. The synergy means lower individual doses can be used while achieving greater total GH output.
GHRP-6 + GHRH Analogs (General)
The same synergistic principle applies to any GHRH analog, including tesamorelin and sermorelin. The GHRP-6 component provides the acute GH pulse amplification while the GHRH analog provides the sustained baseline elevation.
GHRP Rotation Strategies
Some users rotate between GHRP-6 and other GHRPs (GHRP-2, ipamorelin) within a cycle to manage appetite effects. The peptide stacking guide covers rotation strategies in more detail. For example, using GHRP-6 at pre-meal windows (where the appetite stimulation is welcome) and ipamorelin for the bedtime dose (where hunger before sleep is undesirable).
