Ipamorelin vs CJC-1295
Research Compounds Compared

Ipamorelin and CJC-1295 are two research peptides frequently studied in the context of growth-hormone secretion. They act through different mechanisms and are often examined together. This guide compares them strictly as laboratory research materials.

What Each One Is

Ipamorelin is a synthetic pentapeptide studied as a selective growth-hormone secretagogue — in research models it acts at the ghrelin/growth-hormone-secretagogue receptor. It is noted in literature for its selectivity.

CJC-1295 (No DAC), also known as Modified GRF 1-29, is a synthetic analogue of growth-hormone-releasing hormone (GHRH). In research models it acts at the GHRH receptor. The "No DAC" form lacks the drug-affinity-complex modification.

Both are supplied purely as reference research compounds. North Peptides UK makes no claims about effects in humans, and nothing here is guidance for human or animal use.

The Core Difference

The two act on different receptors in the pathway that regulates growth-hormone secretion: Ipamorelin at the GH-secretagogue (ghrelin) receptor, CJC-1295 at the GHRH receptor. Because they engage complementary points in the same research pathway, they are frequently studied together as a pair in models of GH-secretion regulation.

Handling and Reconstitution

Both reconstitute the same way, in bacteriostatic water. As 5mg vials, a 1–2ml solvent volume is a common choice for a clean working concentration. Add the solvent down the side of the vial, swirl gently, and refrigerate the prepared solution. Our reconstitution guide covers the concentration arithmetic.
