CJC-1295 + Ipamorelin stack explained

Why two peptides that target different growth-hormone pathways produce a stronger combined pulse in research models than either alone.

CJC-1295 and Ipamorelin are routinely studied together because they activate complementary pathways that converge on the same outcome: a stronger, cleaner GH pulse.

Two pathways, one outcome

CJC-1295 is a GHRH analog — it engages the growth hormone–releasing hormone receptor. Ipamorelin is a selective ghrelin/GHS-R1a agonist. Combined, they hit two switches on the pituitary at once.

Why selectivity matters

Older GH-releasing molecules tended to spill into cortisol and prolactin pathways. Ipamorelin's selectivity is one reason it has become the default ghrelin-side partner in research protocols.

Peptides referenced in this article

Peptide	Category	Summary
CJC-1295	Growth Hormone Support	CJC-1295 (no-DAC) is a 30-amino-acid GHRH analog that triggers pulsatile growth-hormone release from the pituitary. It is most commonly paired with Ipamorelin in research protocols for a stronger combined GH pulse.
Ipamorelin	Growth Hormone Support	Ipamorelin is a pentapeptide growth-hormone secretagogue. It is valued in research for its selectivity — stimulating GH release with minimal cortisol or prolactin effect — making it the default ghrelin-side partner for CJC-1295 protocols.
Sermorelin	Growth Hormone Support	Sermorelin is a 29-amino-acid GHRH analog representing the bioactive fragment of natural growth hormone–releasing hormone. It has one of the longest track records of any GH-supporting peptide in clinical-research literature.
