Why they are combined
- CJC-1295 (a GHRH analog) raises the baseline growth-hormone signal
- Ipamorelin (a GHRP) triggers a distinct pulse
- Together they produce a larger release than either alone, with little effect on cortisol or prolactin

FAQ

The no-DAC form (Mod GRF 1-29) is short-acting and pairs with the pre-bed pulse; the DAC form is longer-acting. Which fits depends on your protocol.
Before bed on an empty stomach is the commonly reported timing, to reinforce the overnight pulse.
