Ipa/CJC is a research blend of the growth-hormone secretagogues Ipamorelin and CJC-1295 (no DAC) studied for stimulating endogenous GH and IGF-1 secretion; research protocols typically start near 100 mcg of each subcutaneously at bedtime, building toward ~300 mcg each.
It has been studied as a research tool for stimulating endogenous growth-hormone and IGF-1 secretion, with interest in body-composition, recovery, and GH/IGF-axis research contexts.
Research on the secretagogues reports a rapid rise in plasma GH within roughly 30 to 60 minutes of administration, while changes in downstream markers such as IGF-1 are studied over days to weeks.
It is commonly combined as the Ipamorelin and CJC-1295 (no DAC) pairing itself, and in research discussions is sometimes considered alongside other GH-axis or recovery-oriented peptides.
In research settings the blend is typically administered by subcutaneous injection, often once or more daily and frequently timed before sleep, with the no-DAC form chosen for its short half-life to approximate natural pulsatile GH release.

Ipa/CJC is a research blend of two growth-hormone secretagogues that act through complementary pituitary pathways.
Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) and a selective agonist of the ghrelin / growth-hormone-secretagogue receptor (GHSR-1a); research has characterized it as one of the most selective secretagogues, stimulating pulsatile GH release without the cortisol, ACTH, or prolactin elevations seen with earlier compounds. CJC-1295 (no DAC), also known as modified GRF 1-29, is a synthetic analog of the first 29 amino acids of growth-hormone-releasing hormone (GHRH) that binds the GHRH receptor on somatotrophs and raises intracellular cAMP.
Combining a GHRH analog with a ghrelin-receptor agonist has been studied as a way to amplify endogenous GH output through two distinct receptors. Neither component is FDA-approved; both are handled as research compounds, and human data remain limited compared with preclinical work.
