The CJC-1295 Ipamorelin Stack refers to a specific, synergistic combination of two synthetic peptide compounds administered together to optimize the pulsatile release of endogenous Growth Hormone. CJC-1295 is a Growth Hormone-Releasing Hormone analog designed to have a prolonged half-life, which acts by stimulating the anterior pituitary gland to secrete Growth Hormone. Ipamorelin, a selective Growth Hormone Secretagogue, works by mimicking the ghrelin hormone, further enhancing Growth Hormone release while suppressing somatostatin. This combined regimen is clinically utilized to promote lean body mass, improve sleep quality, and support cellular repair and regeneration.
Origin
CJC-1295 was developed in the early 2000s as a modified GHRH analog with a Drug Affinity Complex, significantly extending its duration of action compared to older GHRH peptides. Ipamorelin, a highly selective secretagogue, emerged from research focused on developing compounds that specifically stimulate Growth Hormone release without the undesirable side effects, such as increased cortisol or prolactin, associated with earlier secretagogues. The “stack” concept itself is a clinical application, leveraging the distinct but complementary mechanisms of both peptides to maximize the physiological benefit. This therapeutic pairing represents an advanced approach in peptide endocrinology.
Mechanism
The combined mechanism relies on a dual-pathway stimulation of the somatotroph cells within the pituitary gland. CJC-1295 binds to the Growth Hormone-Releasing Hormone receptors, initiating a robust, sustained signal for Growth Hormone secretion. Simultaneously, Ipamorelin binds to the ghrelin/Growth Hormone Secretagogue receptors, amplifying the GHRH signal and promoting a more natural, pulsatile release pattern. Crucially, Ipamorelin also mitigates the negative feedback loop by decreasing somatostatin activity, which normally inhibits Growth Hormone release. This concerted action results in a significantly enhanced and physiologically appropriate release of Growth Hormone into the systemic circulation.
