CJC-1295
A short-acting GHRH analog studied for pulsatile growth-hormone release.
A cleaner pulse.
CJC-1295 without DAC - also called Modified GRF (1-29) - is a stabilized fragment of growth-hormone-releasing hormone. Without the DAC modification it is short-acting, producing a pulse of GH release that more closely mirrors the body's own rhythm.
At a glance
The GHRH side of the synergy.
The growth-hormone axis has two upstream levers: GHRH (the 'go' signal) and ghrelin/GHS (the amplifier). CJC-1295 occupies the GHRH side.
Without DAC, it does not bind albumin for extended action, so it clears quickly. Research interest centres on preserving the pulsatile pattern of GH secretion rather than flooding the system - which is why it is rarely studied alone.
Not all claims are equal.
- GHRH-receptor binding and GH stimulation (characterised)
- Pulsatile GH release preserved vs continuous analogs
- Synergy with GHS compounds documented
- Downstream IGF-1 elevation in studies
- Body-composition signals in limited research
- Comparisons of DAC vs no-DAC kinetics
- Long-term human outcomes
- Anti-ageing positioning
- Optimal research dosing windows
How it works
GHRH receptor
Agonist at pituitary somatotroph GHRH receptors.
CharacterizedPulsatile release
Short action preserves natural GH pulse architecture.
ResearchIGF-1 axis
GH elevation feeds downstream IGF-1 signaling.
DownstreamSynergy
Combines with GHS agonists for greater pulse amplitude.
